> Superpower is sort of like our Starlink moment

Great analogy if it pays off.

I'd wonder how it competes with nuclear for scale and existing gas turbines for cost and efficiency.

I can see some issues there. Spacex was in a unique position to do starlink as about the only cheap launch provider whereas there are many existing gas turbine producers. Also the gas turbine thing is a bit of a temporary fix to get power for the AI bubble. Longer term they'll probably use more environmentally friendly solutions?
