I really want to see a heat pump being used to make a real world high temperature process more efficient and cut natural gas use by 40% or so, this might destroy the latest talking point

the problem with heat pump is require quite well isolated building to make it efficient. Also after talking with a friend he had to change all radiators in his parents home since it didn't work well with previous old one he had.
I'm also not sure if heat pump is a solution for multifamily apartments.

no, it doesn't require good isolation. Good isolation is beneficial, like for type of heating.
Radiators don't have an effect on isolation. However, modern radiators usually have a way higher surface area, which allows heating rooms with lower water temperature.
Heat pumps are more efficient if the difference between source and target temperature is closer.
I wonder what the nuclear alternative is... a reactor in each building?
Nuclear heating of such buildings would use heat pumps too.
1. Nuclear district heating.
2. Just electric heating, if electricity is cheap enough. Very simple and cheap.
But yeah, heat pumps make that more efficient. At significant higher investment costs. Gotta do the math of whether it is more efficient overall to invest in an efficient energy producer (nuclear), efficient consumers (heat pumps) or both.
