I’m a bit older than that: I have lived the swing from centralized remote computing (long lines and/or dial in, both to the mainframe) to distributed local computing, back to centralized computing.

I remember datacenters being close to the humans and then migrating to be close to the power supply (check out The Dallas, OR, for example) to now locating where they can and scrambling for power, which has become the bottleneck.

At this point I think there’s a diseconomy of scale with the need for all these ad hoc power systems.

I’m not suggesting a return to the captive “machine room”. I’m saying that instead of a mega-plant, smaller, distributed ones might actually be a local optimum.

(Oh, and I have had a rack full of hardware in a data center for my personal compute for more than a quarter century. So yes, I have some experience in history)
