This story reminds me of the Viking lander biological experiments where NASA initially discovered carbon chemistry favorable to life on Mars. But it turned out, there were inorganic explanations to the observed data. In short, they had not done the preliminary work of understanding the inorganic chemistry of Mars. The recent life on Venus story reminds me of that Viking experiment in that our understanding of inorganic chemistry of the atmosphere of Venus is probably far from complete.
