There's this interview on omega-tau of a couple of plasma physicists(?) working on a fusion project in the UK, and there was this funny moment where one of them said that fusion was almost definitely going to work at some point, simply because the problem was so complex. The interviewer, a software engineer by trade, was extremely surprised, and asked him how complexity could be an advantage. The physicist replied that it means that there's a lot of variables you can fiddle before you start coming up against real physical limits. It sticks in the mind because you can sort of see why a scientist would think of fusion as a definite, next-few-decades thing, and at the same time, that doesn't mean it in the engineering sense of, these reactors will actually be just like a nuclear or coal plant.
