Why breaking a good business?
What should really be addressed are:
- Acquisitions of competition or easily-reproducible products. Examples: WhatsApp or Blogspot.
- Landlordism, which has de-facto replaced capitalism, and is the main modus operandi of Western banking system, with boom/burst cycles of debt-financed property pyramid (not "property ladder"). It is really a modern form of feudalism.
Silicon Valley managed to escape landlordism by decentralization of its business. Which is nearly impossible for real industries. Besides real industries are not as profitable, so landlordism has effectively killed them in most western countries. UK is a perfect example.
- Wealth concentration, which could be resolved by land value tax and exponential progressive tax. Exponential, because wealth concentrates somewhat exponentially due to economy of scale.
As for Google, AI indeed may kill its core business. My personal usage of Google Search dropped 20x.
