We will likely see a lot of potential inhabited planets.
Quite a while yet before we will be able to detect life or technology.
We likely will refine our instruments to that point eventually.
Might require an advanced probe to get beyond the heliosphere with very sensative instruments though.
Might be twenty to thirty years, which really is not that long.
We have been considering the question for a lot longer.
Whatever works, use it.
A good idea stands on its own value independent of authorship.
If it stands or falls on the credibility of the author, maybe it isn't such a good idea.
