I would love for this hypothesis and the other pessimistic ones that explain the radio silence to be proven wrong of course.

'overlapping time frames' is a big snag, I agree.
The universe is really, really big and distance = time delay - even at
Those at the same level as us are probably too far away and at the
same tech level for too short a period of time.
Even if we do detect signals they will be from the aliens distant past.
And obviously more advanced aliens don't get to do big tech or spam
the galaxy - because we would see the results.
Maybe the drive towards intelligence means that civilisations gain
great power and either self-destruct or are forced into a quiet,
strictly controlled system in order to avoid destruction. It probably
all happens in the blink of an eye (in age of the universe terms).
