Sneaker

Sneaker (pronounced snee-ker)

(1) A high or low shoe, notionally intended to be worn when playing sport or other recreational activities, usually with a rubber or synthetic sole and uppers of canvas, leather or a synthetic material (sold as “a pair of sneakers”).

(2) One who sneaks; a “sneak”.

(3) A vessel of drink (a now archaic UK dialect form).

(4) A large cup (or small basin) with a saucer and cover (Indian English, now largely archaic).

(5) In biology, as “sneaker male”, a male animal which pretends to be a female to get close to a female, thereby increasing their chance of mating.

(6) In marine hydrology, disproportionately large coastal waves which can without warning appear in a wave train.

1550s: The construct was sneak + -er.  The origin of sneak is uncertain.  It may be from the thirteenth century Middle English sniken (to creep, to crawl), from the Old English snīcan (to creep, to crawl), from the Proto-West Germanic snīkan, from the Proto-Germanic sneikanan or snīkaną (“to creep, to crawl”) which is related to the root of both snail & snake.  Similar forms include the Danish snige (to sneak), the Swedish snika (to sneak, hanker after) and the Icelandic sníkja (to sneak, hanker after).   Alternatively, there may be a link with snitch, also of uncertain origin.  Snitch may be an alteration of the Middle English snacche (a trap, snare) or snacchen (to seize (prey)), the source of the modern English snatch.  A parallel evolution in Middle English was snik & snak (a sudden blow, snap).

The alternative etymology is as a dialectal variant of sneak.  The noun emerged in the 1590s as a development of the verb (as implied in “sneakish” in the sense of “creep or steal about privately; move or go in a stealthy, slinking way” and most etymologists have concluded it was probably a dialectal survivor from the Middle English sniken from the Old English snican, from the Proto-Germanic sneikanan.  The –er suffix was from the Middle English –er & -ere, from the Old English -ere, from the Proto-Germanic -ārijaz, thought most likely to have been borrowed from the Latin –ārius where, as a suffix, it was used to form adjectives from nouns or numerals.  In English, the –er suffix, when added to a verb, created an agent noun: the person or thing that doing the action indicated by the root verb.   The use in English was reinforced by the synonymous but unrelated Old French –or & -eor (the Anglo-Norman variant -our), from the Latin -ātor & -tor, from the primitive Indo-European -tōr.  When appended to a noun, it created the noun denoting an occupation or describing the person whose occupation is the noun.  Sneaker is a noun; the noun plural is sneakers.

Reader's Digest published a number of maps illustrating regional variations in the way things are described in the US.  While they didn't seem to indicate there was a costal v flyover linguistic divide, the Mason-Dixon line did seem to have some influence and there was something of an east-west divide.  One outlier however was "sneakers" which was found predominately to be prevalent only around the north & south Atlantic coasts, the rest of the country preferring "tennis shoes" while there were pockets in the Mid-West where "gym shoes" had traction.  The publication noted their map represented only the dominant form and that all forms (and other) could be found throughout the land.

According to Google Trends, in on-line shopping, while the numbers bounce around, they do so within a range and "sneakers" remains statistically dominant.

The noun sense of sneak as “a sneaking person; person of selfish and cowardly temper and conduct” dates from the 1640s a development from the verb; by 1700 it was used to describe “the act or practice of sneaking”.  The transitive sense of “stealthily to insert” was known by the mid-seventeenth century while that of “partake of or get surreptitiously” dates from 1883.  The phrase “to sneak up (on someone or something)” was in use by 1869.  As an adjective (in reference to feelings, suspicions etc) it was used in the sense of “not openly vowed, undemonstrative” from 1748 while the “sneak-thief” (one who enters through unsecured doors and windows to steal) was first so describe in 1859.  “Sneak previews” were originals viewings of movies held before their public release for friendly critics and others likely to provide helpful publicity, the phrase first used in 1938.

The noun use of sneaker to describe certain rubber-soled shoes was in use by at least 1895 and thus (even if tangentially) linked to the use in the 1590s sense of “a sneak; one who sneaks around”).  The use for shoes was of course based on rubber-soled shoes being essentially noiseless in contrast to those which leather soles which were usually fitted with protective metal heel & toe plates to reduce wear.  A slang term for any soft-soled (usually rubber) shoe was “brothel creeper”, based on the idea that men who frequented such places preferred to do so silently so as not to be conspicuous.  The original term was actually “sneak”, first documented in accounts of prison life in 1862 as prisoners’ slang for both the wardens who at night wore “India-rubber shoes” and the shoes themselves.  The same issue was noted by the Nazi war criminals held in Spandau Prison between 1947-1987.  The prisoners had complained the heavy boots worn by the guards disturbed them but when the authorities issued rubber-soled footwear they found it harder to undertake un-noticed their many surreptitious activities.

There are a number of alternative names for the shoes.  Some are obvious such as “basketball shoes” or “tennis shoes” and “sports shoe” is a classic generic but plimsole has also endured in some places.  That was based on the “Plimlsoll Line” (originally Plimsoll’s Mark) which was a line painted on the hull of British ships to mark the point the waterline was allowed to reach before the vessel was declared overloaded.  It was named after English Liberal MP Samuel Plimsoll (1824-1898), a strident advocate of shipping reforms (many of which were codified in the Merchant Shipping Act (1876) including the “Plimsoll mark”).  Plimsoll came into use in 1907 to refer to rubber-soled, canvas shoe because the band around the shoes holding together the two parts evoked an image of the line on ships.  The spelling quickly shifted to “plimsole” because of the sound association between “soll” and “sole”.  An earlier form was “tacky” (also as “tackie”) which was probably of Dutch or Afrikaans origin, or else from tacky (slightly sticky), a quality associated with rubber, especially before the introduction of vulcanization.  In South Africa, tacky is used not only of rubber-soled shoes but also of car type and often other things made from rubber.

Lindsay Logan, nueva embajadora de Allbirds (the new Allbirds ambassador), possibly on a Wednesday.

In 2022, Allbirds appointed Lindsay Lohan as an ambassador for its "Unexpected Athlete" campaign, focusing on her for the new limited edition of its most successful sneakers (they seem to prefer "running shoe") to date, the Tree Flyer.  The promotional video issued for the announcement was nicely scripted, beginning with Ms Lohan’s perhaps superfluous admission that as an ambassador for running “I am a little unexpected" before working in a few references to her career in film (showing again a rare sense of comedic timing), fondness for peanut butter cookies and the odd social media faux-pas, many of which she's over the years embraced.  The feature shoe is the "Lux Pink" which includes no plastics.  As a well-known car driver and frequent flyer who has for years lived in an air-conditioned cocoon in Dubai, it’s not clear how far up the chart of conspicuous consumption Ms Lohan has stamped her environmental footprint but US-based footwear and apparel company Allbirds claims its design, production & distribution processes are designed to make its products as eco-friendly as possible.  It is a certified “B Corporation”, a system of private certification of for-profit companies of their "social and environmental performance" conferred by B Lab, a non-profit organization which aims to provide consumers with a reliable way to distinguish the genuinely environmentally active from those which cynically “greenwash”.

Lindsay Lohan, Allbirds “Unexpected Athlete Ambassador”.

They’re known also as “gym shoes”, “leisure shoes”, “sandshoes”, “kicks”, “trainers”, “training shoes” and running shoes and in Australia, until the 1990s, one big-selling (and still manufactured) model (the Dunlop Volley) almost universally known as “the Dunlop” and shoe shops do document the difference between “basketball shoes” and “basketball boots”, the latter with an upper built higher to afford greater protection for the ankles.  Interestingly, sneakers (however described) have become something of a cult and many expensive variations are available although analysts see to believe much of the price-tag is can be attributed to profit rather than development or production costs and, like the luxury handbag market, there are claims of “limited availability” and “restricted customer list” but most conclude that usually the only “limit” is demand although some genuine short production runs have been verified, usually for promotional purposes.  They’ve become also an item frequently stolen and among certain demographics, being assaulted so one’s sneakers can be stolen is a not uncommon experience.  Somewhat related to that cultural phenomenon has been the emergence of an after-market for “collectable” or “vintage” sneakers never to be worn and preferably still in their original packaging.  The record price paid at auction is apparently US$2.2 million but some new sneakers associated with celebrities list at as much as US$25,000, intended presumably endlessly to be traded as collectables rather than worn, much in the manner of some of the rarest exotic cars which even the manufacturers admit are produced for just that market.

Floppy

Floppy (pronounced flop-ee)

(1) A tendency to flop.

(2) Limp, flexible, not hard, firm, or rigid; flexible; hanging loosely.

(3) In IT, a clipping of “floppy diskette”.

(4) In historic military slang (Apartheid-era South Africa & Rhodesia (now Zimbabwe), an insurgent in the Rhodesian Bush War (the “Second Chimurenga” (from the Shona chimurenga (revolution)) 1964-1979), the use a reference to the way they were (in sardonic military humor) said to “flop” when shot.

(5) In informal use, a publication with covers made with a paper stock little heavier and more rigid that that used for the pages; Used mostly for comic books.

(6) In slang, a habitué of a flop-house (a cheap hotel, often used as permanent or semi-permanent accommodation by the poor or itinerant who would go there to “flop down” for a night) (archaic).

(7) In slang, as “floppy cats”, the breeders’ informal term for the ragdoll breed of cat, so named for their propensity to “go limp” when picked up (apparently because of a genetic mutation).

1855-1860: The construct was flop + -y.  Flop dates from 1595–1605 and was a variant of the verb “flap” (with the implication of a duller, heavier sound).  Flop has over the centuries gained many uses in slang and idiomatic form but in this context it meant “loosely to swing; to flap about”.  The sense of “fall or drop heavily” was in use by the mid-1830s and it was used to mean “totally to fail” in 1919 in the wake of the end of World War I (1914-1918), the conflict which wrote finis to the dynastic rule of centuries also of the Romanovs in Russia, the Habsburgs in Austria-Hungary and the Ottomans in Constantinople although in the 1890s it was recorded as meaning “some degree of failure”.  The comparative is floppier, the superlative floppiest.  Floppy a noun & adjective, floppiness is a noun, flopped is a noun & verb, flopping is a verb, floppier& floppiest are adjectives and floppily is an adverb; the noun plural is floppies.  The adjective floppish is non-standard and used in the entertainment & publishing industries to refer to something which hasn’t exactly “flopped” (failed) but which had not fulfilled the commercial expectations.

The word is used as a modifier in pediatric medicine (floppy baby syndrome; floppy infant syndrome) and as “floppy-wristed” (synonymous with “limp-wristed”) was used as a gay slur.  “Flippy-floppy” was IT slang for “floppy diskette” and unrelated to the previous use of “flip-flop” or “flippy-floppy” which, dating from the 1880s was used to mean “a complete reversal of direction or change of position” and used in politics to suggest inconsistency.  In the febrile world of modern US politics, to be labelled a “flip-flopper” can be damaging because it carries with it the implication what one says can’t be relied upon and campaign “promises” might thus not be honored.  Whether that differs much from the politicians’ usual behaviour can be debated but still, few enjoy being accused of flip-floppery (definitely a non-standard noun).  The classic rejoinder to being called a flip-flopper is the quote: “When the facts change, I change my mind. What do you do, sir?”  That’s often attributed to the English economist and philosopher Lord Keynes (John Maynard Keynes, 1883-1946) but it was said originally by US economist Paul Samuelson (1915–2009) the 1970 Nobel laureate in Economics.  In the popular imagination Keynes is often the “go to” economist for quote attribution in the way William Shakespeare (1564–1616) is a “go to author” and Winston Churchill (1875-1965; UK prime-minister 1940-1945 & 1951-1955) a “go to politician”, both credited with thing they never said but might have said.  I phraseology, the quality of “Shakespearian” or “Churchillian” not exactly definable but certainly recognizable.  In the jargon of early twentieth century electronics, a “flip-flop” was a reference to switching circuits that alternate between two states.

The other use of flop in IT is the initialism FLOP (floating point operations per second).  Floating-point (FB) arithmetic (FP) a way of handling big real numbers using an integer with a fixed precision, scaled by an integer exponent of a fixed base; FP doesn’t really make possible what would not in theory be achievable using real numbers but does make this faster and practical and the concept became familiar in the 1980s when Intel made available FPUs (floating point units, also known as math co-processors) which could supplement the CPUs (central processing units) of their x86 family.  The 8087 FPU worked with the 8086 CPU and others followed (80286/80287, 80386/80387, i486/i487 etc) until eventually the FPU for the Pentium range was integrated into the CPU, the early implementation something of a debacle still used as a case study in a number of fields departments including management and public relations.

FLOPs are an expression of specific performance and are used to measure those computations requiring floating-point calculations (typically in math-intensive work) and for purposes of “benchmarking” or determining “real-world” performance under those conditions, it’s a more informative number than the traditional rating of instructions per second (iSec).  The FLOPs became something of a cult in the 1990s when the supercomputers of the era first breached the trillion FLOP mark and as speeds rose, the appropriate terms were created:

kiloFLOPS: (kFLOPS, 10³)
megaflops: (MFLOPS, 10⁶)
gigaflops: GFLOPS, 10⁹)
teraflops: TFLOPS, 10¹²)
petaFLOPS: PFLOPS, 10¹⁵)
exaFLOPS: (EFLOPS, 10¹⁸)
zettaFLOPS: ZFLOPS, 10²¹)
yottaFLOPS: YFLOPS, 10²⁴)
ronnaFLOPS: RFLOPS, 10²⁷)
quettaFLOPS: QFLOPS, 10³⁰)

In the mysterious world of quantum computing, FLOPs are not directly applicable because the architecture and methods of operation differ fundamentally from those of classical computers.  Rather than FLOPs, the performance of quantum computers tends to be measured in qubits (quantum bits) and quantum gates (the operations that manipulate qubits).  The architectural difference is profound and explained with the concepts of superposition and entanglement:  Because a qubit simultaneously can represent both “0” & “1” (superposition) and these can be can be entangled (a relationship in which distance is, at least in theory, irrelevant), under such multi-string parallelism, performance cannot easily be reduced to simple arithmetic or floating-point operations which remain the domain of classical computers which operate using the binary distinction between “0” (off) and “1” (on).

Evolution of the floppy diskette: 8 inch (left), 5¼ inch (centre) & 3½ inch (right).  The track of the floppy for the past half-century has been emblematic of the IT industry in toto: smaller, higher capacity and cheaper.  Genuinely it was one of the design parameters for the 3½ inch design that it fit into a man's shirt pocket.

In IT, the term “floppy diskette” used the WORM (write once, read many, ie "read only" after being written) principle first appeared in 1971 (soon doubtless clipped to “floppy” although the first known use of this dates from 1974).  The first floppy diskettes were in an 8 inch (2023 mm) format which may sound profligate for something with a capacity of 80 kB (kilobyte) but the 10-20 MB (megabit) hard drives of the time were typically the same diameter as the aperture of domestic front-loading washing machine so genuinely they deserved the diminutive suffix (-ette, from the Middle English -ette, a borrowing from the Old French -ette, from the Latin -itta, the feminine form of -ittus.  It was used to form nouns meaning a smaller form of something).  They were an advance also in convenience because until they became available, the usual way to transfer files between devices was to hard-wire them together.  Introduced by IBM in 1971, the capacity was two years later raised to 256 kB and by 1977 to a heady 1.2 MB (megabyte) with the advent of a double-sided, double-density format.  However, even then it was obvious the future was physically smaller media and in 1978 the 5¼ inch (133 mm) floppy debuted, initially with a formatted capacity of 360 kB but by 1982 this too had be raised to 1.2 MB using the technological advance if a HD (high density) file system and it was the 5¼ floppy which would become the first widely adopted industry “standard” for both home and business use, creating the neologism “sneakernet”, the construct being sneaker + net(work), the image being of IT nerds in their jeans and sneakers walking between various (unconnected) computers and exchanging files via diskette.  Until well into the twenty-first century the practice was far from functionally extinct and it persists even today with the use of USB sticks.

Kim Jong-un (Kim III, b 1982; Supreme Leader of DPRK (North Korea) since 2011) with 3½ inch floppy diskette (believed to be a HD (1.44 MB)).

The meme-makers use the floppy because it has become a symbol of technological bankruptcy. In OS (operating system) GUIs (graphical user interface) however, it does endure as the "save" icon and all the evidence to date does suggest that symbolic objects like icons do tend to outlive their source, thus the ongoing use in IT of analogue, rotary dial phones in iconography and the sound of a camera's physical shutter in smart phones.  Decades from now, we may still see representations of floppy diskettes.

The last of the mainstream floppy diskettes was the 3½ inch (89 mm) unit, introduced in 1983 in double density form with a capacity of 720 KB (although in one of their quixotic moves IBM used a unique 360 kB version for their JX range aimed at the educational market) but the classic 3½ was the HD 1.44 MB unit, released in 1986.  That really was the end of the line for the format because although in 1987 a 2.88 MB version was made available, few computer manufacturers offered the gesture of adding support at the BIOS (basic input output system) so adoption was infinitesimal.  The 3½ inch diskette continued in wide use and there was even the DMF (Distribution Media Format) with a 1.7 MB capacity which attracted companies like Microsoft, not because it wanted more space but to attempt to counter software piracy; within hours of Microsoft Office appearing in shrink-wrap with, copying cracks appeared on the bulletin boards (where nerds did stuff before the www (worldwideweb).  It was clear the floppy diskette was heading for extinction although slighter larger versions with capacities as high as 750 MB did appear but, expensive and needing different drive hardware, they were only ever a niche product seen mostly inside corporations.  By the time the CD-ROM (Compact Disc-Read-only Memory) reached critical mass in the mid-late 1990s the once ubiquitous diskette began rapid to fade from use, the release in the next decade of the USB sticks (pen drives) a final nail in the coffin for most.

In the mid 1990s, installing OS/2 Warp 4.0 (Merlin) with the optional packs and a service pack could require a user to insert and swap up to 47 diskettes.  It could take hours, assuming one didn't suffer the dreaded "floppy failure".

That was something which pleased everyone except the floppy diskette manufacturers who had in the early 1990s experienced a remarkable boom in demand for their product when Microsoft Windows 3.1 (7 diskettes) and IBM’s OS/2 2.0 (21 diskettes) were released. Not only was the CD-ROM a cheaper solution than multiple diskettes (a remarkably labor-intensive business for software distributors) but it was also much more reliable, tales of an installation process failing on the “final diskette” legion and while some doubtlessly were apocryphal, "floppy failure" was far from unknown.  By the time OS/2 Warp 3.0 was released in 1994, it required a minimum of 23 floppy diskettes and version 4.0 shipped with a hefty 30 for a base installation.  Few mourned the floppy diskette and quickly learned to love the CD-ROM.

What lay inside a 3½ inch floppy diskette.

Unlike optical discs (CD-ROM, DVD (Digital Versatile Disc) & Blu-Ray) which were written and read with the light of a laser, floppy diskettes were read with magnetic heads.  Inside the vinyl sleeve was a woven liner impregnated with a lubricant, this to reduce friction on the spinning media and help keep the surfaces clean.

Curiously though, niches remained where the floppy lived on and it was only in 2019 the USAF (US Air Force) finally retired the use of floppy diskettes which since the 1970s had been the standard method for maintaining and distributing the data related to the nation’s nuclear weapons deployment.  The attractions of the system for the military were (1) it worked, (2) it was cheap and (3) it was impervious to outside tampering.  Global thermo-nuclear war being a serious business, the USAF wanted something secure and knew that once data was on a device in some way connected to the outside world there was no way it could be guaranteed to be secure from those with malign intent (ayatollahs, the Secret Society of the Les Clefs d'Or, the CCP (Chinese Communist Party), the Freemasons, those in the Kremlin or Pyongyang et al) whereas a diskette locked in briefcase or a safe was, paradoxically, the state of twenty-first century security, the same philosophy which has seen some diplomatic posts in certain countries revert to typewriters & carbon paper for the preparation of certain documents.  In 2019 however, the USAF announced that after much development, the floppies had been retired and replaced with what the Pentagon described as a “highly-secure solid-state digital storage solution which work with the Strategic Automated Command and Control System (SACCS).”

It can still be done: Although no longer included in PCs & laptops, USB floppy diskette drives remain available (although support for Windows 11 systems is said to be "inconsistent").  Even 5¼ inch units have been built.

It thus came as a surprise in 2024 to learn Japan, the nation which had invented motorcycles which didn’t leak oil (the British though they’d proved that couldn’t be done) and the QR (quick response) code, finally was abandoning the floppy diskette.  Remarkably, even in 2024, the government of Japan still routinely asked corporations and citizens to submit documents on floppies, over 1000 statutes and regulations mandating the format.  The official in charge of updating things (in 2021 he’d “declared war” on floppy diskettes) in July 2024 announced “We have won the war on floppy disks!” which must have be satisfying because he’d earlier been forced to admit defeat in his attempt to defenestrate the country’s facsimile (fax) machines, the “pushback” just too great to overcome.  The news created some interest on Japanese social media, one tweet on X (formerly known as Twitter) damning the modest but enduring floppy as a “symbol of an anachronistic administration”, presumably as much a jab at the “tired old men” of the ruling LDP (Liberal Democratic Party) as the devices.  There may however been an element of technological determinism in the reform because Sony, the last manufacturer of the floppy, ended production of them in 2011 so while many remain extant, the world’s supply is dwindling.  In some ways so modern and innovative, in other ways Japanese technology sometimes remains frozen, many businesses still demanding official documents to be endorsed using carved personal stamps called the印鑑 (ikan) or 判子 (hanko); despite the government's efforts to phase them out, their retirement is said to be proceeding at a “glacial pace”.  The other controversial aspect of the hanko is that the most prized are carved from ivory and it’s believed a significant part of the demand for black-market ivory comes from the hanko makers, most apparently passing through Hong Kong, for generations a home to “sanctions busters”.

Dongle

Dongle (pronounced dong-guhl)

(1) Historically, a hardware device attached to a computer without which a particular software program will not run; used to prevent unauthorized use.

(2) Latterly, a device (almost always plugged into a USB port) to enable connectivity with other devices, peripherals or networks.

(3) In (very) casual use, any small USB device. 

1980: First recorded in 1980, shortly after the debut of the original IBM PC-1 and although often cited as arbitrary coinage, is possibly derived from dangle, given the first dongles dangled from a short cable.  Unfortunately, the advertisement in a computer magazine in the early 1990s which claimed the dongle was invented by an engineer named Don Gall was just an attempt to make nerds laugh and maybe create an urban legend.  Donglegate was a 2013 incident at an IT conference when a double entendre on the word "dongle" led to a complaint.  Dongle is a noun; the noun plural is dongles.  Because of the nature of the devices and the use to which they're put, it's surprising it seems not to be used as a verb; nor have dongling & dongled emerged. 

Parallel-port dongle.

Historically, a dongle was a small (about the size of a box of matches) pass-through device, a piece of hardware which connected to a PC’s 25-pin parallel (then used most often for a printer) port.  It provided usually a form of copy protection and license enforcement in that the software with which it was supplied wouldn’t run unless dongle was plugged-in.  Most PCs had only one printer port (although from the original IBM PC-1 (1981), there was always support for three physical parallel ports and in the early days of the industry it wasn't unknown to see three Epson 9-pin impact (dot-matrix) clattering away, hanging off the one PC) but it was in some cases possible to daisy-chain multiple dongles on the one port and still connect the actual printer (as the last device in the chain).  The parallel dongles were famously robust and reliable but less successful were the early implementations of dongles as USB devices; the problems were not solved until the early 2000s.

Raspberry Pi Nano WiFi dongle.

Dongle has also come to mean just about anything small which connects to a USB port and does something.  Although the definitions were never codified, the convention of use with USB devices seems to be that a dongle is something which in some way is an enabling device for something else (such as connecting to a WAN, LAN, Wi-Fi or a streaming feed) whereas “stick”, “pen-drive” or “key” is used for something self-contained such as a flash drive.

Personalized dongles.

The most familiar “dongles are still the USB flash drives, used for data storage and file transfer, the later a large-scale version of the original “sneaker-net” which described a kind of low-tech “networking” of devices, accomplished by a programmer (wearing sneakers of course), floppy diskettes in hand, waling between machines to copy and write files.  Memories fade but it’s not forgotten just how transformative was the arrival of the USB flash drive.  Although there had been advances in removable storage which meant at least some users were no longer subject to the tyranny of the 1.44 MB floppy diskette, the proprietary devices were expensive and thus relatively rare.  Additionally, the removable media depended on compatible devices existing at each end, something not always possible conveniently to arrange.  On the PCS, the ubiquitous 3½ floppy diskette had shrunk from it 5¼-inch origins but grown from a capacity 180 KB to 1.44 MB and some versions in the 1990s supported 1.8 MB & 2.88 MB but take-up was slow, the BIOS (Basic Input-Output System) support needed by the latter attracting little support from manufacturers.  Thus the enthusiasm which greeted the early 16 MB USB flash drives early in the century too grew to the point that in 2024 2 TB sticks are available and 4 TB prototypes have been demonstrated.  That process also attracted the interest of economists who noted that even by the standards of IT hardware, the unit cost reductions have been dramatic: the early 1 GB sticks were advertised at US$300 yet by 2024 1 TB (1024 or 1000 GB depending on manufacturer) were advertised at under US$150.  Curiously (and unusually for the industry), just who “invented” the USB flash drive remains contested.
