I would not be so optimistic.
Sure, plenty of exo planets being found, in just a decade since the first, the numbers have been staggering.
But! In most cases the exo solar systems, or what we can detect of them so far, are most unlike ours.
Mainly featuring huge, often bigger than Jupiter, worlds orbiting much closer to the parent star than Mercury does the Sun.
You won't get Earth like planets in these.
Solar systems like ours, with it's stability, with at least one planet just the right distance from a single, stable star, with some giants further out to absorb many incoming comets, allowing intelligent life to rise, with only mass extinction events rarely, you get the picture.
Ones like ours might well exist, but they might well be uncommon, or least at very great distances from each other.
Being as the nearest star is an unimaginable distance from us, using current or reasonably projected technology, it aint going to be like Star Trek.
But being in the Galactic 'suburbs' as we are, allows further stability, much increasing the chances of Earth like planets with life.
Being nearer the centre of a Galaxy, more stars closer together, much too unstable, too many Novas etc, too often, too close.
It would be nice to think that the emerging imaging technology could allow detection of Earth like planets, maybe sooner than we think.
But if we succeed, then what?
Too far to go directly, any radio transmissions from them, or lasers perhaps?
Whatever the answer to that, do we send similar?
A big cultural question for sure.
