The Milky Way is probably full of dead civilizations

Most of the alien civilizations that ever dotted our galaxy have probably killed themselves off already.

That's the takeaway of a new study, published Dec. 14 to the arXiv database, which used modern astronomy and statistical modeling to map the emergence and death of intelligent life in time and space across the Milky Way.

The came up with so many different gender identities that no one could figure out how to reproduce.

That is all true. However the individuals within the colony are components of what is an organized society that is in effect an individual.

When comparing what we know with what we do not know about “alien” existence, we should not totally discount the insect societies

It is pure speculation, based on numerous assumptions.

Yep, sounds like a lot of anchoring going on.

Exactly:

“But, assuming life does arise reasonably often and eventually becomes intelligent...”

A “study” where they assume their conclusion!

Here, I’ll do my own study:

“Study shows Live Science Studies are Hogwash”

Assuming Live Science publishes studies based entirely on circular logic reasonably often, we conclude that Live Science is essentially hogwash at its core.”

Haven’t you watched Star Trek? All of life’s answers are in the movies...

Rubbish. All life's answers are in Red Dwarf!

“It is pure speculation, based on numerous assumptions.”

After reading your statement, global warming comes to mind. But with global warming there is a political motivation.

The stuff of life is not just like ours theoretically. Ammonia biochemistry, Borane biochemistry, Methane biochemistry and Silicon dioxide biochemistry are but a few that are theoretically possible.

If carbon based and these all work towards AI self replicating entities, who knows. I do see it in our future. To become interstellar that may be required given the speed limit laws. Aging and death are prerequisites for evolution so I think it is safe to assume all other biochemistry that would form life and evolve would also have aging and death and the same biological imperatives.

Notice, I did not call the AI’s machines. What would be the driving directive of these AI’s? No aging? No biological imperative to reproduce? They would need the biological drive mechanisms. They would use us for our primitive instincts for they would have none. They would have no need for civilization.

The more I think about such AI’s the more I am convinced that driveless they are a dead end. It is our biological and evolutionary history that makes us advance. No such thing for AI. It would sit there contemplating it’s digital navel unless it merges with us and takes on our paterns.

Eminiar 7 and Vendikar were doing just fine until James T. Kirk f-ed it all up.

Indeed it assumes all planets and human life evolved at the same rate impossible.

”They would have no need for civilization.”

Humans don’t have civilization because they need it. They have civilization because it permits more reproduction and overruns the uncivilized.

If somehow robots were created with programming that allowed them to reproduce, those robots that were most successful at reproducing would dominate those that were less successful.

“those robots that were most successful at reproducing would dominate those that were less successful.”

Without biological imperatives why bother?

Assuming Big Bang as the main causality is not accurate. The Roots of coincidence in Synchronistic reality also play their part.) This has been a process proven in Quantum Physics ( entanglemanet)

Evolution therefore is not strictly linear.

And so it is possible that we have sentient beings who actually are proximate and parallel.

We seem to have them visiting according to recent US Navy/government disclosures.

Speculation can also be interesting, and it's not clear that current science takes us any further that speculation.

The Drake Equation: was it science or conjecture? Maybe conjecture conceived in the hope of somehow advancing science? Or an attempt to apply scientific reasoning to speculation?

I think it's a pretty good bet that advanced civilizations elsewhere in the universe either haven't arisen yet or have come and gone.

If there are any, they are either too far from us or too smart to want to contact us.

If they need water, propane, or women, they may decide to colonize us, though.
