What tax breaks? I’m not aware of any.

Look at sports stadiums. Cities think they need them and cut huge tax breaks for the teams. Then the Oakland/LA/Oakland/Vegas Raiders holds the cities hostage. So, I’m thinking the infrastructure buildout, zoning, water, electricity capacity upgrades, not to mention tax breaks to entice movement to the location are greatly subsidized by taxpayers. I also wonder if after the blowup if the water and power capacity can be bundled and sold similar to the water rights in many parts of Southern California.

I can't see a taxpayer bailout of AI companies. However a lot of stock market value that ordinary peoples savings have gone into would evaporate.
