Possible explanations:

1. A culture sufficiently intelligent to communicate and/or travel between stars would also have gained the ability to destroy itself, and given enough time, eventually will. That window might be fairly narrow. Only 0.0001% of the Milky Way is within 100 light years of earth. Radio waves like we have been generating for 100 years become indistinguishable from background radiation before they even get to our nearest star neighbor, four light years away. The alternative is to blast out strong signals, which must be narrow. It might take too long for an advanced civilization to cover the entire galaxy with a strong signal during the brief window before it destroys itself, and the chances that the signal and an alien planet just happen to intersect during the brief window in which it can receive the signal but before it destroys itself is seems vanishingly small. It's kind of the Drake Equation in reverse, only the numbers get smaller and smaller instead of bigger and bigger.

2. Or, it may be that the advanced civilizations that endure are the ones best at hiding themselves, thus avoiding becoming the target of advanced, belligerent civilizations.

Regarding your question, I don't think AI will save us (and may be complicit in advanced civilizations destroying themselves) but I don't think aliens will ever have the opportunity to.

Just a thought. Throwing it out there.

Although we feel we are moving so fast on the information super highway, nothing can stop us, comparatively to aliens, maybe are at a Neanderthal level?

Perhaps we cannot detect them or see them because they are so advanced and we are not. If that is the case, AI is not going to do much to help the situation.

But of course I truly have no idea.
