If there is life in the Proxima Centauri system, and it has the technological capability to get to the Earth, I think they already know about us.

Serious question: how could they already know about us? Are you simply assuming they have advanced signal detection technologies that match their space fairing capability?

Perhaps they periodically send probes like Oumuamua that report on nearby systems.

I would venture a guess that all so-called intelligent life seeks make use of anything that it can get its hands on and order it according to its will. If this is true, then you really don't ever want to meet other intelligent life. At best they would integrate you into their economic system, just like we integrate people with lower intelligence into our economic system... or underdeveloped countries for that matter.…

That’s a closed minded view of intelligence. There’s a level above exploitation where you value other intelligent life and cherish it.

Humans cherish their pets. Aliens will cherish humans. Can intelligent life however leave things that they know about alone to do as it wishes without any interference whatsoever? No. In the short term maybe, but in the long term it's impossible. Why? Because either it's under control or it's a threat. Either you are a beast, in which case you become a beast of burden. Or you a barbarian, in which case you should be subdued. Or you are an ally in which case you must be integrated. Or you are food which must be farmed and eaten.

Heck maybe in the long run aliens have more to fear from humans than humans have to fear from aliens. But it's not going to end well for one of them in the long run.

I prefer a Dark Forest strategy for approaching the universe. If anything, we should be thinking about how to emit less radiation that can be traced back to Earth into space. Best case: aliens send us technology via morse code. Worst case: relativistic projectile from advanced civilization destroys Earth. https://en.wikipedia.org/wiki/The_Dark_Forest

I just finished reading the series a few days ago. That's how I look at our universe now.

That sounds like a hope/belief, not a fact.

There may be levels of regard for intelligence that are below pets. See, for example, "To Serve Man". [1]

Let's hope that there are no interstellar laws against shining lasers at other star systems.

The Vogons may come by and destroy Earth.

I'll knowingly violate HN's rules to say that's a Vogon conclusion.

At this point I think I would rather take our chances with the aliens since we are going to destroy ourselves anyway.

For being such a cynic about humanity you're awfully optimistic about aliens.

How we would agree on a handshake? Aliens don’t know English let alone Morse code.

But any alien that can build a receiver knows math, and understands physics, and probably has come to similar conclusions about computation. They might be so different from us that communication would be impossible, but it's not likely.

If nothing else, you can draw simple two-color pictures by sending pixels in a NxM grid, where N and M are both primes. Enough minds thinking about the problem will eventually figure it out.
