With Weir's assistance, the fundamental computational unit of the original world's first-generation computer, the vacuum tube, immediately found an equivalent in this world.
Moreover, this thing is genuinely more impressive than the original world's tube because, even by the 21st century, it was quite challenging for human processing technology to create vacuum tubes as small as a grain of wheat.
As for those miniaturized tubes, those are already transistors, not vacuum tubes.
This is also why the first-generation computer was so massive. After all, combining eighteen thousand bulb-sized vacuum tubes would essentially be impossible without a space as large as hundreds of square meters.
Moreover, even though the first-generation computer was designed with eighteen thousand vacuum tubes, it never reached its maximum design computational speed because those tubes would constantly fail and generate copious amounts of heat during computation.
