Datacenter REITs do not directly own all those scarce wired up and powered Nvidia chips.
Conventional wisdom is that building datacenters is easy, but maybe the CW is wrong on this? If it were easy, companies would not be talking about spending $1500+/kg to put datacenters in orbit. Note that they assume they can get the chips either way, they just need somewhere to run them and they are saying it will be easier to get them orbital than to literally do what Digital Realty does now.
Really out of intellectual curiosity, do you know where this falsehood originated? Obviously new power generation is being built all over the world (US adding 86 GW this year, for example[1]), much of it solar. But I keep seeing this persistent claim.
