Apparently it IS possible to make IC’s at home, obviously nothing approaching 5nm transistor gates and therefore the equivalent of lego blocks to precision machined parts… but anyways:

I know absolutely nothing beyond the lego-brick level of building and watercooling machines. No EE chops whatsoever… but this stuff is so interesting to me and maybe one day, cost and space no object, having a palatial garage or workshop to muck around in… Just knowing it’s possible really is the half of it.
