Interesting. If solar/wind and batteries continue their downward price trajectory we may never see commercial hot fusion on Earth, not because it's impossible but because it could never be economically competitive with the giant free gravitational confinement reactor at the center of the solar system. Fission and fossil fuels would eventually be eaten too, though I think you might still see some use of them in regions that are isolated and have very poor solar and wind options.
Fusion would be very important in the far future for the potential of interstellar probes or even interstellar migration. AFAIK it's the only power source that could enable flight at a meaningful (e.g. double digit) fraction of the speed of light.
