Sometime in the next twenty years. Economically viable fusion power is always 20 years away and has been for the last 50.

Frankly I’m thrilled to see them wasting a bunch of time and money on it.

    Maybe you're right. But what if they do make progress? That would change a lot of things, wouldn't it?

      It's not clear that it would; the cost of renewable power has crashed so dramatically over the past ~15 years that it is now difficult for anything else to compete. Even if one were to acquire a fusion reactor completely for free - if benevolent aliens saw fit to drop one off as a welcome-to-the-neighborhood gift, perhaps - the turbines and generators necessary to make use of its output would cost enough that investors would make a better profit just building more wind or solar instead.

      Fusion reactors, could they be built, might well change a lot of things in the polar regions, and perhaps on the Moon; but the era in which fusion power could have radically changed life in the habitable regions of Earth seems to be on its way out.
