No. The mainstream expectation has pretty much always been that locations conducive to life would be reasonably common; the results of the last couple of decades don’t overturn the expectation, they reinforce it with hard data. The controversy has always been on the biological side: whether going from the proverbial warm little pond to a technological civilization is probable (in which case much of the Great Filter must be in front of us) or improbable (in which case we can’t say anything about what’s in front of us one way or the other). For what it’s worth, I think the evidence is decisively in favor of the latter view.
