Datacenters are being built for AI. What happens when you remove the AI workload?

Don't get me wrong. I don't mind when some tech bros burn billions of venture capital & nothing much (?) comes out of it.

But those datacenters embody a lot of resources. Raw materials, complex/resource heavy manufacturing processes for IC's, servers, networking gear, etc etc.

I sure hope that doesn't go to waste when the AI bubble pops. Datacenter stuffed with AI optimized hardware any good for general engineering? Science projects? Weather prediction? Web hosting? ...??
