The criticism for commercial fusion is very similar. Most noise you hear in the news is about something generating more heat than power is put into the plasma.

Most noise you hear in the news is about something generating more heat than power is put into the plasma. But that's a very misleading thing for commercial power generation because not all the power spent on heating the plasma actually goes into the plasma, not all the power that comes out of the plasma can be turned into power, and there's other things that also require power for the whole thing to work.

Most news about commercial fusion is ‘X had a big investment round’ or ‘Y made a really hot plasma’, and if we were in the world where a startup's tokamak hit ignition (we're not), we'd be in a world actually qualitatively pretty excitingly close to net energy, even if it didn't break even end to end.
