To me, datacenters, especially for AI (which tolerates an extra hundred ms of latency quite well) seem like an unusual form of development. Many forms of development have similar downsides: they destroy green space, they can be noisy, they compete for energy resources [0], etc. On the flip side, though, most new developments add substantial value: jobs, tax revenue, increased industry around them, local availability…
the law addresses exactly this. it greatly overtaxes datacenter in green spaces and lowers taxes in former industrial areas.
Regarding whether it's a good development drive... I can tell you, most companies could save a shitload of money by buying a few pallets of machines and racking them in a... datacenter.
I see our monthly AWS bill, I highly doubt we'd be spending that in datacenter bills.
