Fuck that guy and fuck data centers, but this meme is misinformed.
The biggest problem with our current grid is power distribution, as in getting power from the production source to its destination (your house). We absolutely have production issues, but even if we resolve those, we still need to contend with the distribution bottleneck.
Most, if not all of these datacenter plans and include built in power production. Whether it is Google's geothermal, meta's nuclear, or whatver, the power production for the datacenters are meant to be relatively close to the actual.
EDIT: Let me be clear. Almost all of these dedicated power production facilities for datacenters WILL BE subsidized (or fully paid for) by local electric consumers and tax payers in the form of taxes, bonds, and electric bill fees. They are willing to do that for datacenters but not to upgrade our infrastructure (the grid) so that we can transition to EV's.
