We can, and we should, do both. Most of the money raised by MIT's ARC / SPARC project has not been taken away from wind and solar - it's extra money that people chose to invest because, financially, it looks like a decent gamble (or, in some cases, even without looking so profitable, but a step in the right direction, and some people value that). I'm a big believer in wind and solar, although their intrinsically intermittent operation causes me to also worry about baseload power options, and nuclear fusion is the most attractive and promising development in that field. I think it's stupid to look at one part of the solution and not at the other(s).
