Summary

Samuel Schindler, a philosopher of science, presents a nuanced critique of AI-driven scientific discovery, focusing on the discovery of new phenomena. He contrasts this with the traditional focus on discovery of ideas. He introduces a dilemma: supervised learning, by design, cannot discover phenomena significantly different from the training target, making it ’epistemically narrow’. Unsupervised learning, on the other hand, faces the ‘aggravated artifact problem’ due to the opacity of deep neural networks, making it hard to distinguish real effects from artifacts. He illustrates the first horn with AlphaFold, which is excellent at predicting protein structures but cannot discover anything else, and with a thought experiment about binoculars that only see trained objects. He addresses the counterexample of Halicin, an antibiotic discovered via AI, but argues it was still a known molecule and the AI was trained to find antibiotics. He then discusses the second horn, emphasizing that while DNNs are operationally transparent, their complexity makes them opaque, hindering the validation of new phenomena. He concludes that while AI can be a powerful tool, its design limits its ability to make truly novel discoveries, and scientists must be aware of these limitations.

Critical Evaluation

Value of the Information & Strength of the Argument

The talk provides a valuable philosophical analysis of the epistemic limits of AI in scientific discovery. Schindler’s argument is well-structured and clear, using a dilemma to frame the discussion. He effectively uses concrete examples like AlphaFold and Halicin to illustrate his points, and he acknowledges counterarguments, which strengthens his position. The argument is solid, though it relies on a particular definition of ‘discovery’ as the discovery of new phenomena, which may be contested. The thought experiment with binoculars is particularly effective in conveying the idea of epistemic narrowness.

Scientific Rigor, Source Quality, Title Accuracy

Schindler demonstrates scientific rigor by referencing key literature in philosophy of science, such as Kuhn’s work on scientific revolutions, and by discussing recent AI developments like AlphaFold and Halicin. He also cites philosophers working on opacity, such as Katherine Creel. The sources are appropriate for the argument, though they are not exhaustively listed. The title accurately reflects the content, and the talk is well-organized. The speaker’s expertise is evident, and he presents a balanced view, acknowledging the successes of AI while highlighting its limitations.

Contribution & Novelties

The talk offers a novel philosophical framework for understanding the limitations of AI in scientific discovery, particularly the concept of ’epistemic narrowness’ and the ‘aggravated artifact problem’. It contributes to the ongoing debate on AI and science by providing a clear distinction between discovery of ideas and discovery of phenomena, and by highlighting the design constraints of deep learning. The argument is original and thought-provoking.
