No Stupid Questions

No. Because any advanced civilisation capable of sending a colony ship across light-years to another planet is already so far outside of our current technological ability that it matters precious little.

We would be easy to colonise either way. Doubly so if they have some form of FTL technology to make that trip in reasonable time.

But there's also an argument that anyone who can do so would have a much easier time not dealing with all of that and just colonising an uninhabited planet, or outright using materials to make a thing to colonise instead.

Probably not.

I also don't see why any spacefaring civilization would have any interest in colonizing inhabited planets. It would just be more hassle for the same resources you could get on lots and lots of planets. If they have the technology for interstellar flight, they can probably extract whatever they want from wherever they want. Regarding living space, you wouldn't even need planets, there are far more efficient structures you could devise when you don't have to limit yourself to only what nature has provided.

I would think the same so-called AI that told us to eat rocks regularly, or that thinks it's still 2024, or that "hallucinates" other stuff will make conquering our planet harder. Particularly, if these aliens are unaware of the concept of deception.

In that it will lead to the complete collapse of our society and eventual Extinction of our species? Yeah probably

I don't think I understand what the point of colonization would be. At some point, the cost of keeping slaves exceeds the benefit of the "free" labor you get from them; likewise with colonial administration. I think if a species had access to the kind of energy capabilities necessary to make an Alcubierre drive run, then that's functionally a post-scarcity society for a number of reasons, and the only possible reason they'd want to colonize or enslave is if they're just kind of hard wired to go out of their way to be major league assholes, even by human standards. Even if you somehow figure out a configuration of an Alcubierre drive that makes it so you could power it with a conventional energy source, that still bumps us way up towards post-scarcity because of all the cheaty/hackey bullshit we can now do in space. Deploying even a small array of solar panels around the sun to beam as much electricity as we could want to wherever we want would become a trivial task. Oh, an asteroid with sixteen quadrillion dollars of gold? Ez. Just pop on over and scoop up as much gold as you can fit on the ship. Want to colonize and mine the moon for a laugh? No problem, just pop on up there and set up your tent, no giant fucking rockets needed, that'll be two seconds, please. Transporting goods, people, and cargo across the earth becomes comically fast and easy, no more need for big ass jets and airports. The Alcubierre drive would probably have a bigger impact on our QOL than the discovery of electricity.

Why bother sending humans at that stage?

Send the AI to colonise the place and treat it as a tourist destination.

Lots of Alien theme with the newly created OP account.

Are you the one whispering into every CEOs ear about AI?

Aside: Yes - more susceptible to electronic warfare.

I just assumed they would not want what we produce and just have the planet.

Your question assumes a disconnect between labor and AI systems. AI is built on mounds of cheap labor already. It’s going to have to replace things like mines and miners and a TON of labor all the way up the chain (including data center upkeep). It we can do that and build this thing capable manufacturing the autonomous robots that replace human labor, then humans would be in a pretty good place technology wise to defend ourselves. We’re also talking like many many many years in the future when we could do this. We’re far more likely to run out of resources and be forced to be a multi planet species to seek out this dream.
