No, rare intelligence and to a lesser extent rare earth remain as convincing as ever. Potentially habitable does not mean life sustaining, and given the lack of strong biosignatures on any of the examined near earth exoplanets, I’d say that there is indeed increasing evidence that life of any kind really is that rare, much less intelligence.

It is just absurdly hard to get conditions right for microbes to form on a reasonable timeframe is a solution after all.
