The higher-ups were skeptical of the concept of computers
It’s arguably dumber than that. The higher-ups treated R&D like any other centrally-planned ordeal, which meant a bunch of incredibly smart people in different countries were at each others’ throats for the privilege of trying to build a thing… rather than just building multiple things and picking the ones that worked.
When it was a 5-ton, room-filling affair - called the Small Electronic Calculating Machine, because all programmers are the exact same kind of dork - building exactly one kinda made sense. When the west had three competing 6502 minicomputers for like a hundred bucks each, it was just tight-fisted control for the sake of political grandstanding. The fuckin’ BBC rolled out a better centralized computing standard.
The root problem is having “a bicycle for the mind” in a country that restricts travel.
