For example i notice that the latest chips are 3 nm & below, & over the last decade i’ve seen it shrink little by little. What is it about this process that more money needs to be poured into each die shrink, & why couldn’t we just jump from 90nm to 3nm instead pf 65nm etc etc?

That little word “just” is doing a whoooooole lot of heavy lifting. 20 years and hundreds of billions if not trillions of dollars worth of research and manufacturing development. It’s not economically viable to spend 20 years bringing a product to market, so instead you bring something new and improved to market every few years to ensure revenue generation even if you know it’s not the theoretical best thing you could possibly do given another decade of work.
