Oh, extremely unlikely for a number of reasons. And neat if it happened as well. But it would just be so, so disappointing compared to a second origin of life

Oh, extremely unlikely for a number of reasons. And neat if it happened as well. But it would just be so, so disappointing compared to a second origin of life within the solar system or even compared to proof of some form of panspermia or natural seeding of life from planet to planet that it would be a lovely delayed "fuck you" from 2020 if we spend the next 20 years confirming the existence of microbes on Venus, retrieving samples, and finally sciencing enough to realize, goddammit, this is just recent Earth bacteria adapted to a novel environment.
