There is a lot of intelligent life on this planet but almost none of them give a fig about electronics. And even those that do have only a tiny (mostly empty) bubble that their first manipulated waves have even reached. They expect to be around for millions of years, but can’t plan ahead for the next hundred. So even if a couple of million civilizations managed to survive for tenthousand years after discovering electronics, their electronics would not even make it across their galaxy while they existed much less to the next one even if they had ears sensetive enough to hear it. And with the probability of two civilizations overlapping in many billions of years the probability drops in inverse to the distance apart.
The whole speed of light issue is very disappointing. And if a way around it could be found that would be nice, but until there is so much as a concept of how to do it, the belief in it has the same probability as any other beliefs. If such be the case even the closest stars the could be reached might not be visited by the same species as left to go visit.
