Not to be a grinch, but I followed a lot of his videos, and I think he has not yet actually put 2 transistors on the same die, it's the technological threshold for an IC. I think he is working on making patterns (and that's interesting, because nobody is working on cheap masking), he made some individual transistors with masking tape, but not combined yet. But his videos are very cool, and I'm looking forwards to more. I didn't realize he was that young.
