Like it has been for the past 30 years (which, I assume, was the joke here.)
If fusion research was funded adequately we'd probably have it by now, but I don't know if it's the energy lobby or what that means that it's chronically underfunded. An actually working fusion reactor design would bring about such an upheaval in the energy markets that I wouldn't be surprised if plutocrats had a hand in making sure the research receives orders of magnitude less money than it should.
Existing energy conglomerates (ie, oil and gas) probably send their army of lobbyists around the world to spread FUD about fusion. Thus minimal funding. 🪦
It's not limitless, you still need fuel. Especially tritium doesn't really occur naturally because of its extremely short half-life, current plans for ITER involve breeding tritium from lithium in the fusion reactor. The closest to limitless power we have is PV.
Tritium is a convenience, not a necessity. If researchers manage to build a functional fusion reactor which captures the energy, we can find substitutes.
