Sam publicly and uncritically supporting this really does not engender trust in his leadership at OpenAI for the future.

Regarding nuclear and electricity some of my priors:

1. China's plan to build 10 GW nuclear annually for the next 15 years provides a useful upper bound on what's possible without democracy; note that it will still be only 10% of generation in 2040!: https://bsky.app/profile/jrfhanger.bsky.social/post/3lpjszv7li22m

2. There is the US's absurd NIMBY proceduralism, and then there are the limits of how quickly we can physically site and construct co-located large-scale data centers and (presumably) AP1000s. Don't underestimate how much of China's 10GW/year depends on the preceding decade of ramp-up with a much more ruthless command-and-control culture at all levels and a much larger skilled workforce to draw on (there are dozens of specialized job types involved).

3. Oh, and the decade-ahead commitment itself. The US has been yo-yoing on policy every 4 years since 2008. "We" Biden-admin got less un-serious about nuclear via the LPO, then "we" Trump-admin did a 180°.

4. Data centers would be MUCH easier to interconnect if they agrees to tolerate a few hours of down-throttling a year—requiring the local utility to ask for and implement that demand response. Some might.

5. The single most interesting important question in energy: how we are going to capture the value of 60% annual growth in "world" (Chinese) solar panel production? New solar capacity, in panels: 2024: 600GW, 2025 1TW ... 2030 13TW!? With corresponding cost/watt reductions. Note that the world grid is ~3TW (9TW capacity), China 1 TW of that, US 0.5, California 0.05.

6. Batteries are on a similar curve. It might be easier to power a 500MW data center with, say, 2GWh of on-site batteries plus existing grid capacity plus arbitrary new generation anywhere in the service area than to get a dedicated AP1000 built. Plus that key demand-response agreement!
