That is true and could be a way for anthropogenic panspermia to occur. My totally uneducated gut feeling is that the chemists and geologists are going to get more out of this finding than the biologists though. Theres a lot of cool rocks and an atmosphere full of SO2 (a pretty decent reducing agent) on venus - and abiogenic phosphenes are found in other parts of the solar system. Some chemical reaction with perhaps some recently expelled volcanic ash (there was recent evidence that it might still have active volcanic activity right?) seems more plausible than life, but hey, thats why we have experiments to see if the unlikely is true after all!
