It doesn't matter how useful the tools are if the companies providing them don't make enough money to justify their investment. Hundreds of billions of dollars

It doesn't matter how useful the tools are if the companies providing them don't make enough money to justify their investment. Hundreds of billions of dollars a year are being spent building datacenters which produce only tens of billions of dollars in revenue, and those datacenters are depreciating assets. This cannot continue indefinitely. Is it reasonable to expect the AI industry to be produce revenue at the rate of a trillion dollars a year or so, within the next five years, as it will have to do to avoid a crash? I very much doubt it.
