I guess we should find a cheap fab plant and start selling these to hobbyists?

cant. they chose a "non commercial" license.

Find a cheap plant, ask for donations and give them away for free?

On a related note, I wonder how difficult it'd be to take the netlists and turn this into something that can be thrown on an FPGA.

FPGAs (as the name implies) work at the gate level, not the transistor level.

Would it not be possible to take these netlists and map them to gates? It seems like at least the majority should be possible to automate.

In some cases yes. In some cases (i.e. the mask-programmable ROM) you would have to deviate significantly from the original design to provide duplicate functionality on a transistor substrate you don't control.

Can't wait for the 8088 schematics, now that was a groundbreaking CPU!

I think it matters quite a lot in terms of educating undergraduate electrical engineers.
