IIRC the one of the first times a group put timelines to a fusion reactor they had time vs funding level of something like 20 years/50 years/never, and the funding level that actually materialised was below the 'never' amount and yet it started the 'always 20 years away' joke. Now I think the timeline was probably still optimistic but fusion is also obviously a very expensive thing to develop and while it's gotten a lot of funding it's still at the 'in the background' level.
