Personal anecdote on the curse of dimensionality: there were many tweets/substacks back in 2020-2022 with diagrams of biochemical pathways where every protein or molecule had arrows pointing to lots of other proteins, concluding: "Oh my God! That's how SARS Cov 2 causes amyloid plaques! (insert disease here)". Initially I thought I needed to study biochemistry in order to understand these arguments. Then I concluded that they are all nonsense. Just So stories. Exactly like my old field -- magnetically-confined plasmas for controlled fusion. (In fact, plasma physicists can boast of 70 years -- not a mere 20 -- of irreproducible/useless results.) Every ion/electron in a plasma interacts with a billion nearest neighbours -- analogous to the curse of dimensionality. By induction, I would argue that virtually nothing in biology/epidemiology/virology is truly "understood"; only that certain observations can be made, which may or may not allow one to make useful predictions. As for commercial R&D, let's forget the "R" and focus on the "D".

A very thought provoking article, thank you. The insights from the Denis Noble interview are very interesting.

Hubris seems to be a big problem in the genomics field of science (?). Perhaps if CRISPR can ever realise its dream, the hubris gene could the first target to be edited out of future generations to ensure a better world.
