Early computer scientists were so optimistic. They beleives with a few kh of ram and a mhz of cpu they could do anything. Ai, consciousness, ml, language, text to speech. Now we spend gigs of ram on web forms. So gibson saying yeay 3MB of ram would probably be enough for a consciousness in cyber space, is very optimistic but fitting.
I remember when Johnny Mnuemonic came out and he was hauling 320 GB in his brain and that was a WHOA moment.
Not sure if "optimistic" is the right word - you could still do a lot with tiny memory or CPU footprint, but that's difficult to do if a large part of tech have adopted to either not care about the waste ("space is cheap"/ "the RAM would just sit there unused if I didn't use it") or lately even based technologies on the paradigm of using as much of it as possible. That was the explicit idea of bitcoin, but even AI development goes by the logic of "what would happen if we just made the model twice as large?"
The last iteration is "tokenmaxxing" where you try to spend as many tokens as possible first and then find out if it got you anything useful.
3MB of RAM but 120PB of storage. Sure you're paging a lot but
I saw a chrome tab this week that had Gmail with an empty inbox idling at 2.8Gb. Hard refreshed the page. Still 2.8Gb.
Maybe there is a parable here: don't fear the man that wants thousands of gigabytes, fear the man that only wnats 3 MB.
"Early computer scientists were so optimistic. They beleives with a few kh of ram and a mhz of cpu they could do anything." -- this isn't true, much less the stuff layered on top (conciousness!?)
I like to remember that Gibson wrote Neuromancer on a typewriter and hadn't even touched a computer till (I believe) half way through Count Zero.
