N+5 years off, where n is the current year. We'll get there one day!

IIRC, most of the people that actually work at ITER don't expect to live to see commercial fusion.

We've achieved controlled ignition several times, but there's a lot of steps still between that and delivering fusion power to your local grid, and I don't think I would trust anyone to give a concrete timeline.

I really thought Polywell Fusion would be the trick, but Australians (and probably the US DoD) have good evidence it doesn't "scale" in a way that will give a energy-positive/fuel-negative cycle. https://en.wikipedia.org/wiki/Polywell#University_of_Sydney_experiments

It's going to be a hell of a lot faster with all those oil wells burning

no no no, it's

years off.

We keep getting closer, but by smaller increments.
