For comparison, patio11 post(ed) a lot of great stuff for free with tips and ideas, and then sold his courses and consulting services https://www.kalzumeus.com/greatest-hits/
A few years ago, he went from consulting to a normal job, so most post are old, but IIUC he now is in consulting again. I still make comments with links to his old post because I think his advice is good.
That idea of Intel spinning off and developing it's own TSMC sounds great! What other factors have prohibited from someone else developing a more viable TSMC competitor in the US?
The idea isn't exactly unique, in that AMD did it and called it Global Foundries(GF)[1]. Then in 2015 IBM divested their foundry capabilities and sold them to GF as well. It hasn't been a stellar experiment which is largely laid at the feet of the challenge of managing that business.
