I’m just going to go ahead and say this now, do not expect most windows games to run better on Linux than windows. Typically the case is when you find a well optimized game that is CPU bound, or is natively vulkan. Anything else, expect comparable framerates.

I agree with every point you make except for the desktop environment front end.

While it is nice to install a distro with a given desktop environment OOTB, you can always change it, and even have multiple ones installed at the same time. This is typically a better approach to testing out desktop environments because you don’t have to reinstall every time.

I completely agree with everything you said except for ONE little thing:

You are grossly misrepresenting how far that can is kicked down, for the worse. It doesn’t kick it down a couple thousand years, it kicks it down for if DOZENS of millennia assuming we stay at the current energy capacity. Even if we doubled or tripled it, it would still be dozens of millennia. First we could use the uranium, then when that is gone, we could use thorium and breed it with plutonium, which would last an incomprehensibly longer time than the uranium did. By that point, we could hopefully have figured out fusion and supplement that with renewable sources of energy.

The only issue that would stem from this would be having TOO much energy, which itself would create a new problem which is heat from electrical usage.
