Fleuret amplifies debate: AI can't slash wet-lab experiments in unmapped biology

François Fleuret amplified a debate over claims that AI will "experiment far far less" in biology. The rebuttal: that assumes biological systems are closed environments with all fundamental rules known. When half the relevant signaling pathways and post-translational modifications aren't even mapped in training data, deductive reasoning only yields highly confident hypotheses that still need a Western blot to falsify — a sharp note on the limits of AI for Science in data-incomplete domains.
