but maybe these alien programs are led by the equivalent of the sub ceo guy.
lmao
the ftl travel required to visit each other is likely impossible
related to this, I was under the impression ftl does not actually permit backwards time travel, although I get that there are other objections. for years my go-to reason to dismiss ftl was always that it allowed backwards time travel and grandfather paradoxes

Do you have more information on this? My understanding was that, from the perspective of relativity, traveling faster than light was actually identical to traveling backwards in time.
I’m on my phone and don’t have a link off the top of my head but tldr events can appear backwards in some reference frames but you yourself can’t actually go back and interact with your own past.

Depends. Accelerating yourself faster than light is impossible. But folding/bending space and then travelling at below-FTL speeds in that warped space is completely possible. Thus - warp drive.

Ignore capitalist pessimistic paradoxes, embrace soviet time travel

*I think Sabine Hossenfelder has a vid about it
