"where little progress is made on a hard problem does not mean that it will never be solved"

Never said that. But if fusion scientists say since 50+ years, that they are allmost there, then it is a pretty good indicator, that there probably also won't be a working fusion plant in the next 15 year's.

That would be true if we had no other data to go on, but we do: the fusion triple product, which has to exceed a threshold for net power. The JT-60 tokamak in Japan reached a triple product in 1999, using D-D fuel, that would have barely exceeded breakeven if they'd been using D-T. Fifty years ago we were nowhere near that close.
