I assume you are against them due to the silent forest hypothesis? Better not announce ourselves, because anything out there might not be friendly to us?

The dark forest hypothesis assumes that it's easy to travel between stars, so interstellar conquests are possible. But it doesn't seem to be the case.

There are no material goods that can justify the material and energetic expense of any interstellar travel. You'd be far better off just using a particle accelerator to forge any chemical element and then assemble them into molecules using nano-replicators.

The best you can do is to send information, possibly with the help of gravitational lensing.

Sci-fi mode on: given that the potential galactic civilization is going to be information-based, who's to say the Earth is not already under attack? An interstellar fleet of large invasion ships with soldiers is not feasible, but a small drone with an AI that connects to terrestrial networks and steers the civilization towards collapse is possible. I'd start investigating if TikTok algorithm developers got some nudges from a weirdly knowledgeable source.

That sounds like an invisible malevolent force trying to destroy us, himm, sounds familiar :).

Material, no. but we know with absolute certainty that Earth will stop being habitable for humans at some point. So assuming any intelligent race, human descendent or otherwise, still exists on this planet, it will have to eventually move. It's just pure luck that we evolved when we did. But there are valid reasons for interstellar travel(other than you know, pure curiosity).

		I wouldn't characterize it as "moving". Any excursion outside of the solar system will not be done by anything resembling a modern human, full stop. It may be plausible to send some sort of robot with some sort of nanomachine hoo-hah off in the direction of a nearby star, to seed life there. But no living human will ever leave the heliosphere.

They already let an illegal alien buy the last election.

The vast space of everything seems to me that any intelligent life eventually discovers physics to get out of this dimension. Dune space feudalism is unlikely
