It’s not just paranoia either, there’s a lot of research into things like autonomous war drones (basically AI robots), which are designed for a very specific job. And the reason I think this is important is because once AI/AGI starts replacing most jobs, we lose the thing that gives us leverage – our value as workers. That's not necessarily my opinion, but what I suspect their opinion is – the people with the power.

Look into Assembly Theory as well: https://en.wikipedia.org/wiki/Assembly_theory They already developed some kind of chemical printer for simple molecules.

There's also no point in talking what can be done today, since such a project would take quite a while, both to assemble and get anywhere close to destination. Just because we cannot do it today doesn't mean it shouldn't be considered as a possible approach since we might get there in 30-50 years, which is nothing for the scales of time we're talking about.

Cryo tech is quite primitive, you are fighting to maintain a structure instead of saving its data and rebuilding it later when tech allows. Imagine 3D printing a benchy and freezing it so it stays "fresh" for 50 years (for some potential use at that time), instead of saving the benchy stl file and printing it in 50 years.

Plans for potential human expansion into our galaxy must include potential tech developments, can't block it to the tech that is available today. The way things are going there's no reason to discard full scan and reassemble of a full human being, in some future. Let alone moving consciousness on other type of more resilient hardware.

The most likely way to move in the Universe is through something along the lines of von Neumann probes, which can be small machines sent at relativistic speeds across the whole galaxy, setting up these "spawn" points. Even at 10% speed of light it would take 1 million years to get such probes in strategic points to cover most of our galaxy.
