We can make it so it's never aliens, or always aliens. Public and science opinion has become a free for all lately.

People are so caught up in the 3I/ATLAS stuff, for example. Should we beam a message to it? What should we think of it? It's a circus.

Let's go back to Boyajian's Star instead. Can we really be sure the dimming is not caused by a mothership coming from that direction? It explains everything, right? Maybe that's how they communicate, by sending a paper plane and opening a large occlusion origami that says "we come from this general direction" (I'm cosplaying Avi Loeb here, satirically).

There's something about interpretation in all of this. Space is full of radio signals. We determine lots of them to be natural (with good reason).

I'm afraid proposing "we should answer" (in case of electromagnetic signals) could lead to a scenario in which people are encouraged to believe something without the means to verifying it. Some idiot group could do it just to increase the popular optimism about space in order to induce a favorable perception on the development of space technologies with the ultimate goal of just bumping some industry with money. It's the kind of world we live in right now, unfortunatelly.

If we want to be serious about humanity's place in the universe, first we need to be serious about our home right here. I don't think we're mature enough to have responsible control over technologies that could be used to send a powerful signal into space.

I've always thought that the public reaction to aliens in Contact was precisely, painfully accurate. Panic, cults, religions, the typical human response to something huge, unknown, and unknowable.

You should see the movie Don't Look Up. It is even more painfully accurate portrayal of our times, and it eeriely explains why the world's richest men are building and testing rockets and spaceships. (Answer: No, it ain't merely for space tourism or mere profits. They know their misdeeds will ruin the Earth one day, so they are preparing a Plan B.)

Dude, the movie Don't Look Up is a metaphor for climate change denialism. It has nothing to do with asteroids.

The movie Don't Look Up is still an apt metaphor, because the variable (how the apocalypse will happen) may change, but the outcome won't.

The same richest elites that refuse to acknowledge and do anything to revert climate change, will do nothing (except try to escape Earth in spaceships) if and when any humanity detects and anticipates any Earth destroying apocalypse inducer (asteroid/meteor or extreme solar flare) from out of the depths of space.

It's kind of a stretch.

To a more naive, metaphor-blind audience, your mention of Don't Look Up makes it look like the scientists are warning about an alien comet and I'm the one ignoring it.

I'm very familiar with apocalyptical narratives of all kinds, but what I'm approaching here is much different. I'm talking about the integrity of scientific endeavours. In particular, space exploration endeavours.
