Since it's long, here's some takeaways:
- We are in a bubble. We were already in a tech bubble in 2022 but AI growth and capex started a new one.
- The growth of monopolies not only damages GDP but transfers money from ordinary workers to the rich.
- Tech advantages for a company rarely last long, soon they become commoditized and everyone has the tech.
- Productivity improvements do not mean more profits, but can cause employment issues if new jobs don't get created fast enough.
