I kindly suggest watching the whole video. While the beginning is  high- level technical, the discussion quickly moves to the complex but symbiotic semi ecosystem and then onto geopolitical concerns. I tried to skim the video but found the focus changed constantly so missing a bit risked losing the thread.

What's of great interest is the discussion of all the players and the roles they fulfill, from Nvidia to TSMC, TI, and the thousands of unnamed others. The upshot is that companies that gain a toehold in a market segment often go on to dominate their chosen specialty. For instance, the capability gap between Global Foundaries and TSMC is growing and likely to become insurmountable in 10 years. There is a place for Poet as a fabless design house in all of this, and now is the time to lay claim to it.
