I think the end goal is not to extend the life of our (inherently flawed and limited) biological bodies, but to replace them.

We aren't going to explore & colonize space in fragile meat bags that require food, water, air, stable pressure, gravity, and temperature. Even on Earth, supporting a ballooning population isn't going to be easy.

The goal is to digitize consciousness, and there is still a lot to figure out before we get there. I don' think it's possible to make human bodies as we know them "immortal"

Sorry, I'm using determinist to mean hard determinist. I intentionally avoided incompatibilist since that also includes libertarianians.

A determinist would agree that it’s incoherent… which is why they are determinist, no?

I agree, but I think the difference between the professional and amateur philosopher in that assessment is how they define free will. Professional philosophers who are compatibilists are using a more narrow, very specific definition of free will, while the amateur determinist is using the broader colloquial definition.

Surely you don’t mean idealism in the philosophical sense, because that’s not what idealism is…

Emergent property just means that none of the individual objects that comprise the whole have the property, but the whole does. For example, mortar and bricks don’t have the properties of a wall, but when combined in a specific configuration they do. Still material.

r/futurology is hit or miss, and usually feels more miss than hit. There’s a big Luddite population, and too many “didn’t we learn anything from science fiction movies” comments.
