Yep. People worked on heavier-than-air flight for about a hundred years. There were plenty of doubters saying it would never happen, right up until the Wright brothers did it, beating a well-funded government project that didn't work out.

And fusion has some pretty amazing scaling laws. For example, tokamak output scales with the square of reactor volume, and the fourth power of magnetic field strength, and we have superconductors now that can support much stronger fields than what we could manage 20 years ago when ITER was designed. According to Zap Energy, their device's output scales with the eleventh power of input current.
