Random articles on the clickbait tech press circuits are a far cry from
actual in production use. (See also, IPv8 lulz from last week. )

Very few SMRs are actually running anywhere. Canada approved a 4 unit SMR
project at Darlington in 2020, they didn't start construction on the 1st
until until May 2025, and don't expect that to be online until 2030. 10
years for 300 MW thermal isn't a great value proposition when you can spend
the same 10 years to get a 1GW thermal reactor up.

Large nuclear will unlikely be a solution either. You don't just blow the
dust bunnies off a decommissioned reactor to fire it up again, and even Big
Tech isn't likely to be able to grease the NRC into easing most
regulations. Even the dumbest of politicians is smart enough to know that a
TMI in your district is REALLY REALLY BAD.
