If the electric grid — particularly the interconnection queue — is already the bottleneck to data center deployment, is something on this scale even close to possible? If it's a rationalized policy framework (big if!), I would guess there's some major permitting reform announcement coming soon.
I’ve been advocating for a data centre analogue to the Heavy Press Programme for some years [1].
This isn’t quite it. But when I mapped out costs, $1tn over 10 years was very doable. (A lot of it would go to power generation and data transmission infrastructure.)
