Most skepticism is ratified by subsequent events.
DT fusion doesn't appear to have much to recommend it, since it still requires a thermal cycle like fission or coal, and that keeps its cost high. From an engineering point of view it involves large monolithic plants with very complex and stressed equipment. This seems the opposite of good engineering.
We're constantly being told to take the long term view. Are we only to do that when it's favorable to the technological optimist's case or budget?
If you have to build a steam turbine to convert the energy from your fusion reactor into electricity, it's never going to compete with solar and wind power in most of the world.
Doesn't mean that there won't be applications (if you can make all those lasers compact enough, submarines, ships, and ultimately spacecraft come to mind), but grid electricity is doubtful.
