As a society we have failed to really use fission. Fission does basically everything fusion promises to do. Fission has a absurdly high energy density, the step from oil to fission is far more relevant then the step from fission to fusion. Fusion would mean basically no fuel cost, but thorium is already a waste product and even uranium fuel is a tiny part of any fission plant. Some people seem to believe the fusion is inherently prove against weapons, but this is equally not really true. If you had a working fission plant there would be ways to use it to get what you want to make a weapon. There are some places you might want fusion, mainly in space travel but even there we are not anywhere even close to where we could get to with fission. Open gas nuclear thermal rockets anybody? In sum, I'm not against this reseach but its not a way to solve our problems anytime soon. Fission you could get to run with 60s tech and amazing reactors could be designed within decades and often with comparatively small teams in the 60-80s and somehow we haven't managed to make it competitive. Fusion looks to be far more complex to build in every possible way. How this will be cheaper is questionable to me.
