However if the signal is close enough and/or powerful enough, it might be detectable above natural background
I was thinking the same thing-but it would have to be pretty damn close, maybe 50 light years methinks?
IF we ever got a signal, it would be a message from the past, just like your 'I love lucy' we could be getting messages from a long dead civilization-hell we had two world wars in less than 50 years let alone the cold war. Any species that sent any messages could have died out by natural or unnatural causes, or continued to thrive and that could explain some of the encounters of the second kind.
Maybe Schrodingers' cat could come into the equation, if we do get a signal that civilization could be alive or dead.
Yes, maybe even closer now, but as technology advances, we may be better able to process intelligent alien signals up to 50 light years away. That's still not much given the Milky Way galaxy is 100,000 light years across. One estimate I saw of intelligent civilizations in the Milky way was as low as 10 of them, but even if it's 100 or 1000, there still may not be any within 50 light years.

Meanwhile there are millions of REAL lives currently living in poverty in this country. 😡
That's not going to change by throwing a few million bucks at it. However, if we find aliens and are able to figure out their technology, that could be "so long, poverty!"
maybe SETI hasn't detected intelligent radio signals because more advanced civs don't use radio. communication via quantum entanglement of some means would be far more efficient and fast. maybe radio communication is like smoke signals to them

Nobody should understate the difficulty of detecting alien radio or television type signals. It is difficult in that many places we could search are so distant that the signals may be nearly impossible to detect above natural background noise.

This is pure idiocy.
I've said this before-the universe is full of natural phenomena that emits low frequency radio waves and searching via low frequency radio waves is like trying to single out one person cheering at the superbowl while being blindfolded.
However if the signal is close enough and/or powerful enough, it might be detectable above natural background in which case I hope you'll agree that "I Love Lucy" type television broadcast signals are nothing like naturally occurring electromagnetic radiation.
So it's not idiocy, but it would take some good luck to find a source close enough and powerful enough to be detected. There may not be intelligent civilizations that close to us. Maybe they exist on the other side of the galaxy where we can't detect them.
If we look, we might find something, but if we don't look, then we can't find anything.
All the ideas people have that aliens are already here are entertaining, but completely lacking in any scientific proof.
Or like us maybe their television broadcasts transitioned to cable which can't be picked up like the broadcasts. There could be many reasons.

Communication via quantum entanglement of photons happens at exactly the same speed as radio and television, the speed of light. I know there are research papers saying the entanglement is correlated at least 10,000 times faster than the speed of light, but you need a classical light speed channel to interpret the communication, so it's really no faster.

While we are at it let's throw ten million dollars into EVP research so we can hear the dead talk!

Perhaps, but the $50 million per day that NASA gets of taxpayer money certainly could end it.

What if I told you that $50m a day NASA gets is only 0.5% of our budget. However, our military spending is around 54% of our budget.
Do you still think NASA is the right place to look for cuts?

Or what if there has already been covert mission to star systems beyond ours and the best thing found so far is an animal level intelligence ground hog, puppy, slug thing sucking algae off rocks? I think I`d want my money back.
Millions searching for E.T. or a way for money to change ledgers for whatever BS they want?
in order to meet the NASA objective to search for life's origin
