When it comes to fusion I am always in too minds about statements like this.
On one hand, yeah, it is something that we may be able to wrangle into something useful.
On the other, fusion can be seen as a perpetual motion machine that doesn't defy the laws of physics. It can kind of inhabit that same mind space.
It's so very nearly amazing in several different formats and applications. Net result is it's kinda okayish in a couple of niches.
Similarly there are other competitors for fusion. The difference here is they are orders of magnitude better in most ways. Fission and chemical reactions have much higher power density and vastly lower cost (and fission is already cost prohibitive), renewables are vastly cheaper even with battery or chemical fuel storage. There's not really a good niche for D-T fusion even if we had it today rather than in 50 years.
