Unfortunately due to the complexity and number of challenges, the last rock may fall on your head and knock you back to the bottom again.

I'm not saying it's a valid goal - just until the technology is useful, it's not yet viable.

Compare to unified field theory, the Higgs boson and string theory.

A pessimist is an experienced optimist :)

What are the practical implications of your pessimism?

I don’t understand. Are you a physicist? Why does being pessimistic about fusion give you more free time?

Without going on too much of a philosophical tangent; not about fusion - about everything in general. It allows me to concentrate on now rather than in the future. Now is the only time that is certain. Now is the only time you get to enjoy your life before it's over or your children leave.
