Lu Fan got too much into it.
A simple photolithography design ended up having him design a whole electronic ecosystem that would bring the most out of Carbon-based chips and circuitry.
Carbon chips are faster in comparison to silicon-based chips. They were also very easy to make once the technology was available.
Changing the overall design of things that needed to be changed to ensure efficient use of the chips was easy with MIA helping gather the data.
The precision machines were also designed from scratch, unlike Lithography machines for circuitry, photolithography machines for chips 3.0, or the soon-to-be-released 4.0 required insanely precise mechanical arms to produce.
He also needed a simple AI to handle everything. There was no way he was going to waste time teaching a bunch of grown men how to do this and that.
