Fermi Paradox

[Chas]

My suspicion is two-fold.

It may be that civilizations tend to last only a few thousand years and there isn't much chance for any nearby ones to be extant in the same time period.

It may be that interstellar travel really isn't practical or not even possible in any reasonable way (time, energy).

Wouldn't it a terrible disappointment to spend trillions to travel hundreds of light years to reach a planet with life forms like us....and then find out they really are like us?

maybe we could do something just a little more significant during the next 50,000 years or so ???

LOL humanity will stop existing in few hundred years. Keep dreaming

I voted for two, interstellar travel of any distance is probably either impractical or impossible.  But humans aren't that interesting is another good bet.  I have one more.  It seems every other scifi book I read these days involving interstellar travel by humans includes some sort of moral prohibition on revealing ourselves to species who have not yet invented interstellar travel.  So what if they are hiding from us for our own good?

But ultimately, I don't think we really know how likely intelligent life outside of our solar system really is. After all we only have one example.

At the risk of courting the anthropocentric fallacy, we've not really been shy of finding other cultures and interacting, for better or worse.

I do, however, think that any spacefaring civilization has already had our experiences insofar as it has colonized its own planet, and would perhaps be a little thoughtful.

A little.

Go read The Mote in God's Eye.

Humanity won't go extinct.  We'll 'progress' to what the Moties become.

To put it bluntly

We as a race in whole are boring there is no redeeming qualities to earth for any advance race and or beings would simply
not hold in interests in what we are and what we are doing. They would hold some attention like hey those jack asses finally figured
out how to split a atom. Then hey those jack asses figured out some good medical practices. Then hey those jack asses finally figured out
space flight.

No, you mean you're boring! I'm fucking awesome.

If there's no God then all alien civilizations(millions of them) became extinct because of this

I suspect the answer is 2 fold. Firstly as mentioned before we ourselves have been moving from large over the air broadcasts to cables and smaller more targeted signals. That is a huge consideration. But we must consider the vastness. It's fully possible that a far more advanced civilization is using much more targeted broadcasts then we are now. I would like to mention as well that we do have a plausible theorem for ftl drives, the osbatcle is just the amount of energy. Which may sound high to us now, but may become more easily tackled as we advance.
