I agree with a lot of your points but I do think containers a great solution.
I've been a really big fan of Universal Blue lately. It presents a strong argument for containerizing everything. Your core is immutable and atomic which makes upgrades seamless. User land lives in a container and just gets layered back on top afterwards.
I do think it's interesting that a lot of people seem to think AI is going to take away jobs but understanding AI just a tiny fraction, it seems like the things that are threatened are one that were already micro serviced away like internet search.
We use search everyday and having the best search engine means being the best tech company. These companies are in a race to topple Googles search dominance through providing AI as a service. There's money in them hills if you can train an AI to recommend when and where to go buy the newest shiny thing that solves all your problems.
