My take on this is that our technology advancement is too rapid and we will not recognize E.T. even they litterally banging at our front door.
Most of our technology doesn't go back more than 300 years. Space technology as we know it today is about 70 years old. Meaningful computer evolution
in AI only dates back 10 years.
We have changed our technology stacks so many times in such a small time frame that we have lost serious knowledge in a timescale of decades...
knowledge used to be prevail over 1000s of years - today we create the same amount of information in a matter of hours.
Our first "signal" that was strong enough to propagate throughout space is barely a 100 years old and relatively has only covered about 200 light
years at this point. Well the milky way alone is 100k+ light years wide.
Now Kepler-186f - the first exo-planet to believe to have life - is over 510 light years away. Any radio signal will take another 200-300 years to
"just" reach that system.
We need to assume that if there is any chance of contact - that those on the other side have the technology to actual:
1) discover the signal
2) decode the signal and understand it
3) to have the technology to return a message which will take another 500-600 years.
So we talking almost a 1000 years before we would get a response. Even more if the "other" side is still in their technological infancy.
At our rate of technology advancement - "basic" radio technology will be forgotten at that point or we could not distinct between the incoming message
or the polluted RF spectrum at that point. We already having issues today and have to limit broadcast powers, etc due to the increasing uses in the
different frequency bands.
Then again, we might already left this planet or destroyed ourselves - our transformed our conciseness into electronic form and only "live" as 0's and
That's why I am doubtful that even we make contact and signal arrives here in Earth - we might the one not understanding even it's our technology.
