Why compare it to nuclear rather than what’s currently being used in that area? Coal and gas.
Nuclear is good for providing a stable base load, but having the entire grid be nuclear would be very expensive. And if everyone were to do the same, the market cost of fissile fuel materials would skyrocket.
Lots of solar and wind in the energy mix is a no-brainer.
They said they’d probably have to if Fedora removed support for 32-bit packages, which was a proposal to the Fedora Community (who rejected the proposal).
Long-term, I imagine Valve will have to bundle a 32-to-64-bit abstraction layer, like they already do with a win-to-linux abstraction layer (Proton), and are preparing to do with an x86-to-ARM abstraction layer.
Distros do not want to each duplicate the work of maintaining 32-bit support for all eternity.
