This is exactly right. We are no closer to fusion today then we were 30 years ago. The problem is and always has been containment — or how not to melt a hole through the Earth. I don’t think actual ignition has ever been the hard part of the problem.
We’ll probably be building non-orbiting stationary power generation factories in space and beaming the power down well before they solve the fusion puzzle.
And cold fusion? Cold fusion is a myth, it’s not fusion at all, it’s a chemical reactor.
This is correct.

This is not correct.

This is also not correct.
There is no "containment" issue. "Confinement" refers to the issue of confining sufficient fusion material for sufficient time in a small-enough region at sufficient temperature to maintain a self-sustaining fusion reaction -- achieving what is colloquially referred to as "ignition." It is the only issue there has ever been. And we are not much closer to doing it than we were in the 1950's; we only know more things that don't work.
