compare it to the space program. that didn't really have any directly useable goal. but the technology produced in the process is used everywhere. DT fusion may or may not work. maybe the problems may get solved some day, maybe not. we'll never know if we don't try. and the technology we get in the process is valueable regardless.

Spinoff technologies from space are another "sell the perception" thing. There's a lot of BS there. But as long as the public swallows it, it works to justify the program.

Even if you choose to ignore all that has come from it.. Space is quite possibly the most important thing we can be investing time, money and research into in terms of future advancement and sustainability of the human race.

Huh? Spinoff technologies from the space race are everywhere, to the point that they seem mundane 50-70 years after the fact.

Polyimides like kapton are a good example.
