This wiki seems somewhat out of date. For example OP lists support for P2362R3, but the wiki has that as red.

cppreference is indeed a wiki so you can update it if you’d like. Usually the compiler maintainers do.

That Nevermind baby story paints a nuanced story. It doesn’t seem necessarily like a net negative for him. Much less than the people in OP article.

Also consider cost (in terms of CO2, resource consumption, etc) of building and maintaining the renewable energy sources.

I don't know how this would compare between underwater datacenter, solar panels, wind.

Building and maintaining the non-renewable energy sources also costs CO2, though.
