On a scale from pseudoscience to Hard Science how seriously is Quantum Immortality taken by people who Quantum for a living?

Was mainly wondering because I see it being promoted by things like Kurzesgtat (I know I butchered that) and other popular Science promoters.

Yet anytime I see anyone, even Roger Penrose himself, supposit that mind is any way connected to Quantum phenomenon it is attacked mercilessly and rushed out of the room like a crazed bloodied up goat that somehow snuck into a nursery.

So I am a little confused. By what mechanism would Quantum Immortality even work if science is so sure there is nothing like a soul jumping timelines?

Quantum immortality is not the same thing as the idea that the mind somehow utilizes quantum processes. Quantum immortality is the idea that when you die you go some other branch of the multiverse and live on. The idea is the mind uses quantum processes is usually just a theory about the biological processes in the brain. The latter position is more open-ended and more plausible (we already know, for example, that the sense of smell utilize quantum processes so in general sense not that far fetched; things get more controversial when you start looking at specific theories).
