Remember, any civilization that we find is unlikely to be in their technological infancy like we are. If they survive it and thrive through it, we’ll likely encounter them in a state tens or hundreds of thousands of years more advanced than we are.
According to that logic, no other species is likely to discover our own presence because we aren’t more advanced than they to start with.
Until we actually discover the presence of intelligent life elsewhere in the Universe we cannot assume the level of technology they will have.
They might very well have achieved the same level as us and then become extinct and, as we will only detect that level of tech on their part, we will never know whether that be the case or if they simply followed our own trend of emitting less information pollution.
It’s an example of the halting problem: we’ll only know for certain when we know for certain — until we know for certain we can never be certain that we will ever be certain.
