I agree, but.......
Supernovae are required to create the heavy elements in the universe.
If you shut them off, then future life probably won't develop.

If pre-singularity ET life exists, then it is likely still bound to
the originating planet, like humans. And there may be a lot of early
life, like bacteria, on many planets.

If fast thinking AI exists, then we are in a new ball game. What we
think likely doesn't apply to them.

They don't manipulate the physical universe. They probably move into
deep space. They don't broadcast their presence. Why would they? The
physical universe appears frozen and unchanging to them. Their
interests are in the virtual reality they have created for themselves.

Even if humans survive our singularity we probably won't contact other
fast-thinkers. We will live in our own virtual reality, far from
planetary systems.
