> Sense/Net sure had a lot of employees considering the in-story world had true AGI,
I think there's a simple explanation to this one: there must have been an atmosphere that consumer demand for everything is default insatiable and any excess productivity will be used to increase total production, regardless of products.
If a sub-Wintermute AGI equivalent to Claude Opus class of ours could run 12 completely synthetic TV stations with help of one part-time human overseer, a cyberpunk entity like Sense/Net would have 1000 employees each responsible for six AGI units amassing 72000 total TV channels in its relevant company sub-division alone. Same in the real world today would mean 2400 of its 1000 employees including interim CEO got fired at the end of the week when its 3 AGI units went operational, but works like Neuromancer were written in a different time than ours.
> they don't show people having driver problems,
This one is probably because 1980s home computers didn't have much of the software "stack", plus peripherals were more or less hardwired to RAM buses. Apps ran side by side with guys from Nebraska[1] code, and could read or write to memory addresses where it thinks where the card is connected to, without having to call syscalls and have OS figure out device addresses and bus protocol packet constructions. So it likely wasn't obvious that there will be situations in the future where the mcguffin black box unit would ask an outdated binary build of an outdated framework that would be needed to be pulled from someone's Download folder and/or fixed by 16-hour tinkering(but the Chinese ICE in Neuromancer had security potting, so maybe that was it).
