People are bad at estimating how long it will take to develop something, but everything I've seen indicates that we are getting closer to it being a real thing.
Though I'm skeptical about the safety, as it does sound like it could get pretty explody if the containment fields fail. Or if they fail in just one direction, I wonder if they'd shoot out a plasma jet that fucks up everything in its path.
Even the sun shoots shit at us from time to time, which our own magnetic field generally protects us from.
Not that I'm against fusion power, just not holding my breath that it's going to be all sunshine and no flares.
Not to mention it's pretty fucking arrogant (and dumb) to equate something you want someone to do with something they need to do to survive. IMO anyone who thinks like that should be considered too stupid for authority.
