@@raulrrojas Thank you for this sordid news. This past is as bad as when I missed employment opportunities to enable me to learn to use DOS, Microsoft Windows 1.0, 2.0, and 3.0, plus Wordstar, Supercalc, dbase, earlier versions of Microsoft Excel, PowerPoint, Aldus Pagemaker, Adobe Illustrator, and other programs created in the earlier years. Guess what? I came out much better by using Microsoft Windows XP Professional, and Microsoft Office XP Professional on a new microcomputer I bought myself, than I would working in another men's or women's workplace. I can do better all by myself. Also, thank you for typing to me.

Technology is always much more fascinating when it's in the emerging stage, and you can dream about all the possibilities to come.

[@HKragh]

And now it is up to you to recognize what about our current technology is just as "emergent", and profit big on pointing us unwards. Because I assure you, whatever feels "modern" about the present day, will feel just as dated as what we see here, and even outrageously simple in 20 years. We will think: "Man, did we really do it like this", and "Man, had I only thought about this OBVIOUS next step, I would be the one with the billions". Go nuts, dream about all the possibilities. They are there. And some will notice them, while most will not. I guess one of the big things will be how we interface with technology, as we move away from our clumsy "thumbs on screens".

[@HKragh]

​@mike h You are completely right in terms of THIS domain of computers; The Von Neumann architecture. While clock speeds has increased, and components has shrunk, the basic idea has stayed the same for 70 years... But I assure you a computer in 500 years won't look anything like what we have today. The Von Neuman method is way too linear and waaay too power hungry. And to get things from processor to RAM, and back takes a relatively long time... Big things has yet to come. And especially AI will change stuff (IS changing), because the linearity of current hardware goes so much against what Neural networks really need.

That would be especially when it works right. Otherwise, computer technology would be a hair-pulling experience.

Gary and other tech intellectuals understood Moore's law very well and mathematically would comprehend the bits and bytes of modern day technology.

I love how at a time where almost no one in my home country even knew what an audio CD was, these people were already using CD-ROMs.

[@rafroessolarpowered81]

Same here in Brazil back then. CDs started to become popular about 7 years later, not really popular because it was very expensive having a player or a CD-ROM Drive at the time. It only started to become mainstream in 1994, 95...

[@oldtwinsna8347]

It wasn't very much different in the US consumer market. While the hardware existed in the mid 80s, very few owned one until the 1990s rolled in. It was such a niche driven market that there wasn't much desire for ownership after learning of what they cost. Even the folks with cash to burn were more interested in getting a hard drive to install programs to avoid the slow access time of a floppy and the constant swapping.

[@fattomandeibu]

​@@rafroessolarpowered81 It wasn't until the Playstation that a lot of people here begun using audio CDs. A Playstation console cost less than a CD player as Sony sold them at below production cost to ensure that as many people would buy them as possible, since they got 30% of every game sold they didn't care about the loss on the console. This cause other CD manufacturers to start bringing the cost of their regular players down and started a price war. They did the exact same thing with the Playstation 2 and DVDs and attempted it a third time with Playstation 3 and blurays, but by then people were more interested in streaming.

[@maxxdahl6062]

[@TH3C001]

You can probably include me in "young folk" since I was born in '94, but it's funny, I cannot have a computer without an optical drive. The first computer I built in 2014 with money from a summer job had an optical drive, a CD/DVD burner. My current and second computer built in 2021 also has an optical drive. I still burn CDs for my stereo, or burn drivers to discs for use in other/older computers I own. As a kid playing with the Windows 98 PC my father had CDs were a huge part of the experience, the discs were so satisfying to handle and place in the drive. It feel like the most "computer-y" thing to handle discs and insert or remove them from my computer lol, kinda like handling floppies, or USB drives lol, and its probably a similar sensation fans of vinyl experience when putting an album on their turntable.

[@Germanswisscheese]

I actually laughed out loud at "...You would have to transmit, nonstop, at "1200 baud" for 46 days."

[@Abr3200]

What its a baud?@_@

[@Germanswisscheese]

A baud is one symbol per second, which is one bit per second, or a zero or a one per second. Binary computer code is made of ones and zeros, for instance the letter "k" in binary ascii computer code is "100 1011". It contains eight binary symbols, which are called bits, each letter in ascii binary code can be represented with a string of eight ones and zeros, "L" in ascii is: "100 1100". A lower case L or "l" is: "110 1100". A "$" symbol in ascii is: "010 0100". Because ascii encoding was one of the first widely used computer codes and because each letter or symbol in the code was eight bits long, they began referring to each segment of 8 bits as a single byte. So remember, the eight bit code for "K" is: "100 1011" that is one byte. A baud is 1 bit per second. So 1200 baud is 1200 bits per second or 150 letters a second transferred from one computer to another. Or something like 0.143 kilobytes a second or 0.000143 megabytes per second. To put that into perspective, a modern cable Internet connection usually has a speed of 20.0 megabytes per second. It would take 6 hours to download a 2 minute .mp3 on a 1200 baud connection.

[@Abr3200]

Woooow Really? 150 letters per secon? OMG just imagine how long ill take to download an entire GB of information. So this thing was before the 28mb/s modems (Sorry for my bad English) This is so amazing. How they could do so much with these limited systems and resources.

[@Germanswisscheese]

And that is why I was laughing out loud, it's incredible how far we've gotten in 30 years in computer and data transfer sciences.

[@ArumesYT]

@@Abr3200 Even today a lot of information is being transferred as text. Text-based websites like Wikipedia would still be perfectly usable with a 1200 baud modem; it transfers text a LOT faster than you can read it. Same for Whatsapp or any other messaging service. E-mail too. You really don't need high speed connections as much as you think.

[@0raffie0]

Interesting to see how optical media was the future in 1986 while today it is already deprecated, at least in computing. All this while magnetic media is still very much alive in computing, although obviously we are seeing the beginning of it's demise due to flash memory creeping up on it.

[@jesuszamora6949]

I don't think flash will be replacing tape any time soon. Tape is CHEAP for archival, and still getting cheaper, and requires less effort to preserve it for its effective life, to say nothing of how easy it is to get stuff from old tape to new tape. It's going to be a long time, if ever, before flash replaces tape for archival.

[@cube2fox]

@@jesuszamora6949 I'm pretty sure he was talking about hard disks.

[@jesuszamora6949]

@@cube2fox Well, tape has never really been an HDD format. I can't imagine the load times. o_O But even that, does flash last as long as even HDD, let alone tape? Durability is the key. I don't think flash replaces HDD until it achieves that level of robustness.

[@cube2fox]

@@jesuszamora6949 I don't think he was suggesting that tapes are hard disks. They are obviously not. But hard disks are magnetic like tape. I think you are right in that flash does not have quite as high a durability (in terms of number of write operations) as hard disks, but nonetheless the durability seems to be so high now that it isn't a concern any longer, at least for private customers. Speaking about tape, I think its main advantage is its low price per bit, which makes it well suited for archival purposes. (And even hard disks are much cheaper than flash memory.) Also, if the DVD hadn't been invented, tapes would have been also well suited as video format. Similar to VHS, but digital. In fact there were attempts to introduce such a medium. Its capacity was comparable to Blu-ray discs and as such way ahead of the then common DVDs. Maybe such high capacity was simply not needed back then because Full HD TVs weren't available.

[@jesuszamora6949]

@@cube2fox Not sure if I'd go so far as to say flash is durable enough that the average consumer won't care, as it's only been in a price range the consumer can swallow without being super tech-minded recently, and is mostly seen in tandem with an HDD (running the OS and games while data is kept on the HDD). Perhaps by the time it gets as cheap as HDD (which it will, eventually), the durability will also catch up and we'll see them used exclusively. Used to be winchester drives were incredibly sensitive, and look where we are now. And yeah, I saw a Techmoan video about D-Theater. That kinda highlighted tape's only real issue, and why it's consigned to archival nowadays. Loading. Holy hell, that D-Theater player sounded like an IBM 5150 for how loud it was! They were spinning the reels like crazy, I can't imagine how weird it'd be trying to use them in a PC for normal use!

[@oldtwinsna8347]

Nope. Online connectivity has been in existence for a long time. Consumer level access was common in the 1980s through service providers such as Compuserve, Genie, and Qlink (the predecessor to AOL). These were nationwide services so it operated under the same idea where you connected distantly with (relative) ease as most used a GUI or a pseudo-GUI text menu prompt. Online shopping was in fact available during this time, albeit of course not a fraction of what it became when the commercialism of the Internet unfolded in the mid 90s. These providers relied not on what we know as the internet, but a different standard known as packet switched networks such as Tymnet, or Telenet. You can crudely think of them as private loop based networks across the nation. There were forums where people commented/debated just as we call it as "social media posts" today. Again, not anywhere of the same scale since it was very niche but it did exist!

[@lindaoffenbach]

The big invention by Philips in the late 60s / early 70s but the computer industry (US) was actually very conservatively late with embracing it (at least lagging behind by 10 years). In the Netherlands with Philips HQ, LaserDisc was already available in 1972 for the high-end consumer...

[@PhoenixNL72-DEGA-]

Think that had more to do with the cost of the devices and publishing companies still having to find a use for all that storage space that the average user would find usefull or entertaining. The killer apps that sold CD-ROM drives were after all games like the 7th Guest and later Myst. And of course fully voiced adventure games like Day of the Tentacle also helped. Basically CD-Rom didn't take of until the average PC's performance level became capable of multimedia playback (Audio&Video)

[@oldtwinsna8347]

Took more evolution and refinement over other complementary hardware items. Else, CDROM titles just importing text database stuff, though having some niche in business/education, was pretty boring and stale for the consumer market. Consumers wanted to be dazzled to make the purchase. Sounds cards, for instance, to playback digital samples, took a bit of time to get into the affordably priced market for PCs. Motion video also required some serious horsepower that just was not possible under the original XT or 286 processor. Even the 386 was too slow and only until the 486 came out with its fast integer processor could we get decent stuff done to what we now call multimedia.

Probably Welsh

And 38 years later optical storage devices are obsolete.

[@punishedexistence]

For 1985, this ain't half bad technology, really.

[@PrzeszczepiX]

punishedexistence CD-ROM in 1985 was like a technology from NASA. while even in early 90's, many of us in Europe still used 3.5 floppy disks for data storing. the CD-ROM became a real thing in our PC's on 1994/1995. earlier we only had a stereo music players and these were the only things that used CD discs (for audio only) in our houses.

[@PrzeszczepiX]

and the reason is simple - back on 80's a very few software was released on CD-ROMs, the optical drives were freaking expensive (costed more than entire computer) and only IBM PC's was able to use it (yes, CD-ROM was only IBM compatible for long time, it became for other platforms like Macintosh, Amiga, Atari etc. in 1992/1993)

[@martinkunev]

The video is actually from 1986. Look at 24:54

[@oldtwinsna8347]

The best of tech was just unattainable unless you had deep pockets though. Much of its use was also very limited, so you had this hot piece of technology that was maybe 1/3 of your disposable income for the year and yet it had such little impact in your daily life.

[@davidgamesgitas]

i have seen one with 800mb but they are very expensive

[@davidgamesgitas]

In that time cd got more memory than the harddrive

[@rooneye]

Sorry George, you were wrong! Unlike bubble memory, CD's DID eventually take off and become the standard.

[@straightpipediesel]

Bubble eventually won. Just a different type of solid state non-volatile memory, i.e. flash, which obviously took off and killed floppies, CDs, DVDs, and now hard drives. His argument about software was spot on, and Bill Gates knew it too. Software is expensive and fundamentally a one-time development cost, and it's a waste of money making 3 versions for the sake of supporting 3 OSes, so whoever gains a majority market share will become unstoppable.

Revenge of the hard drives!

[@thedogwooddandy]

George Morrow literally never gets it right re the future of computing.

[@DavePoo2]

Yeah, he go that one totally wrong. He said it would not "fit comfortably" in the environment, and would be too expensive. Fast forward 10 years and operating systems, software, video games & movies would be distributed on optical disk, and CD-ROM drives for the PC were 10x cheaper.

[@thedogwooddandy]

@@DavePoo2 I really try to keep a cool head when he is speaking throughout this series. I realize his contributions to computer history but he certainly was a pompous doof alot of the time when asked about vision and foresight.

4:30 "The enormous capacity of CD-ROMs, about 250 Megabytes per side, ..." I'm pretty sure they always had just one side and never less 650 MB per side?!

[@Moskito844]

just one side, but it was 512 mb at the beginning

[@cube2fox]

@@Moskito844 Do you have a source for that? Both my memory and Wikipedia says 650 MiB.

[@nickwallette6201]

This episode claims 250MB per side, 550MB, about 600MB, and 1GB on a 12” disc, which is a huge demotion in density compared to CD. This is a little before the time when I got into CD-ROM. I wonder if all these systems complied with any of the colored books, or if there were multiple readers out there with vastly different proprietary formats.

[@700gsteak]

The first standard cdroms were mode 1 with 2,048 bytes per block giving 580mb capacity. They then switched to mode 2 with 2,336 bytes per block upping the capacity to 662mb. It was more of a formatting change and didnt change where the data physically stopped on the disc. Later on 700mb and 800mb data discs were introduced which actually reached closer to the edge of the disc as tolerances improved. The 1gb sega dreamcast gdroms were a formatting change to a 800mb disc.

[@cube2fox]

Funny how optical media is dying today due to the Internet.

[@FusionC6]

Optical was dying 15 years ago. DVD and BLURAY were the only reason why it's kinda sorta still alive today.

[@morgorth3242]

@@FusionC6 even usb memory sticks killed cd roms xD

[@ens8502]

It already died

[@oldtwinsna8347]

It's more or less dead aside from the entertainment enthusiasts. There simply are a lot of titles produced that are not available in online distribution format. It's actually only a very tiny amount of motion picture produced that is available online. Your average person, however, is only interested in watching top rated stuff which is all online.

[@christineayres5339]

It's interesting that not a single guest throughout the run of the show appears to be under 40.

[@700gsteak]

Back when pcs were a piece of commerial industrial equipment for big businesses and there was no consumer, prosumer or enthusiast pc market cause it was too expensive

[@jesuszamora6949]

Well, you didn't see a lot of this type of stuff until the IBM clones hit. This was the absolute cutting edge. The early adopter is richer, and the economies of scale make it more affordable to the masses.

[@oldtwinsna8347]

At this time most of the consumer market execs were by-products of the mainframe era computing of the 60s/70s where they acquired most of their knowledge, influence, and wealth.

[@joaogrrr]

*THE ENORMOUS 250MB CAPACITY*

[@ens8502]

250 TB you said???

[@PhoenixNL72-DEGA-]

@08:50 Lol, really? Presenting a layout in book form? They clearly had no idea what they were doing. The power of later encyclopedia's like encarta was that you had powerfull search features at your disposal. The idea of going to a specific "book" and find someone or something there by it's name in that "book" is not how those would be used. Search, Index, Cross links, Categorization those were the powerful features of an encyclopedia on CD-ROM.

[@nickwallette6201]

Technology changes much faster than culture. There was a while there when people scoffed at the idea of CD-based encyclopedias because part of the “joy” of owning a set was rummaging through them and finding things you weren’t even looking for. There was hesitation that the random encounter with an article would be lost. Hence the book metaphor. The demonstrator even says something to this effect - that you can thumb through them like a traditional set. Anyway, it was new, they were blazing a trail, responding to feedback. Etc etc. it got more optimized as the usage patterns developed.

[@kimkimpa5150]

You mean to tell me I can carry around an entire encyclopedia on an optical disc just 4.7 inch wide? SHUT UP AND TAKE MY MONEY!

[@SkuldChan42]

George Morrow is right - this stuff will never take off - now get off my lawn.

[@tamastarczy6262]

That thumbnail tho.

[@Geoffr524]

When you can have a 200gb microSD memory card, I see optical disappearing, and I know Apple had eliminated the cd-rom drive from their small computers.

[@JaredConnell]

Most mobile devices have dropped them. with no moving parts due to the lack of hard drive, DVD drive, and cooling fans battery life goes way up. I bought a laptop about two years ago with no optical drive and the one I bought a few months ago had no moving partfs at all. I've had the battery last almost 8 hours of solid usage, laptops just a few years ago barely got 2-3 hours lol

[@guspaz]

Optical media has the advantage of still being much cheaper. Sony's archival disc archives cost around $57 per TB, while a spindle of regular BD-R discs can hit as low as $16 per TB. That's much cheaper than magnetic hard discs, let alone flash storage (which costs roughly 15x as much), and that's just buying a spindle as a consumer. Bulk orders of optical discs can get much cheaper. It's even rumoured that Amazon based their "Glacier" archival storage service on a massive array of BDXL bluray disc libraries, taking advantage of large economies of scale.

[@FusionC6]

A lot of data centers still use tape drives for storage.

[@700gsteak]

microsd has terrible write cycles. its not replacing optical.

[@oldtwinsna8347]

Man this post shows its age. Now it's 1tb sd storage for not much over 50 bucks.
