But I don’t see power bills getting cheaper as a result of this technology eventually becoming viable. At least not at first. Especially when in the US you have people like Warren Buffet who buys power companies and immediately raises prices by around 50% as a matter of routine.

Ah! Now this is a conversation we can have. (Gets on soapbox.)

With all the talk about cheap fusion energy, no discussion is ever made about how it's going to fit in with our existing capitalistic system, and what happens to all the companies that exist worldwide that currently generate energy using other/classic means.

Do they all go bankrupt? If so, what does that mean to the different economies in the different countries?

Assuming they're willing to go bankrupt in the first place. What about if they fight back, if they flex their political power to prevent the cheap fusion energy from being realized?

Maybe they have governments subsidize them? If so, then so much for cheap energy, as we all pay more taxes to subsidize. At that point then why bother, economically that is. It still benefits the planet, so there's that.

Maybe the world powers decide to do nothing, and just shelve fusion power altogether, to protect their existing interests. Then what happens to the planet, as we get more and more into trouble using fossil fuel energies that harm the planet? Existing renewables (solar, etc.) aren't enough, so something else is needed as well.

We all joke and/or worry about fusion energy being here in 20 to 30 years, and how that 20 to 30 years always keeps sliding into the future, never coming to fruition. But the real problem is going to be once Humanity finally makes fusion power work practically, what does that mean to the status quo in power, and will they be accepting of it, and if not, what does the rest of us do about it?

TLDR: Does old power 'go quietly into that last good night' and allow new power to take over, or do they fight back? And what does that mean for all of us? And the planet?
