We don't have the tech now. Else, they wouldn't have to burn down houses with lasers.

What they have is small nuke generators.
They also have some alien tech that makes energy but can't be replicated.

We will not have the tech until we will never, won't even think about using it for war.

I comprehend why you would think they have the tech locked up, but what they have locked up is stuff that is really only one leap up. I have already given enough knowledge in my posts to recreate it.

We can all live richly as we get rid of the narcissistic psychopaths from positions of control.
