I know a lot of engineers doing chip design in the US. Cutting edge stuff. I know folks working in custom stuff, Arm stuff, Risc stuff.

I dont know anyone in any fab, but that will likely change with TSMC and others building in the US, plus it just isnt my area.

CS as in computer science? Go minecraft. Learn how to play with him. Then learn about redstone. Then you can show him amazing things you can do in minecraft with programming.
