Earlier quoted context omitted.
It's insanely hard. TSMC is so dominant because they have very, very, deep institutional knowledge. Even if you have billions to invest it's not easy to create that, and definitely impossible to do it short term. There's only 3 companies left chasing smaller nodes. Everyone else has given up and are focusing on revenue from high volume parts in older processes.
The only three are Samsung, Intel, and TSMC. Idk why going on with Intel but Samsung should BSs doing better but that institutional knowledge that TSMC has is crazy. They all technically invest in asml that makes the machines. If I had to redo my education I’d get into electrical engineering just for this.
I get the impression it's mostly physics guys.
