Our current math is about as sophisticated as retina + V1 + V2 (which is why that’s all we can - barely - understand). Your full visual cortex etc. would leave QFT in the dust if it was evolutionarily useful.

Yes, but it wasn't. And, nevertheless, we developed QFT, QED, QCD, ..., which are certainly not based on intuition. Other parts of our (collective) brain opened up windows to reality way beyond our perception and intuition.

My point is that our brains running on microscopic data would leave QFT in the dust.

Not *our* brains, which evolution hardwired to work at certain space-time scales and with certain innate physicas (e.g. locality, "objectiness", some space-time equivariance,...). For that to work, we would have to re-evolve different brains and (very) different senses.

Moreover, what brains and physics do is qualitatively different. Brains are prediction machines, unworried about explanations/models. Physics aims at building "good explanations" (as Deutsch puts it). An "intuitive understanding" and a "formal explanation" are different things.

Brains and physics are both predictive and explanatory. And your brain is a better mathematical machine than any math used in physics. (“Intuitive” is a misleading word.)

Not true, sorry. Humans have used arrows and catapults successfully for 1000s of years. However, only 4 centuries ago Galileu explained that all objects suffer the same gravitational acceleration and Newton (using math) explained that arrow trajectories are parabolas.

Try telling psychologists that the brain is not explanatory, or physicists that physics is not predictive. Your System 1 understands the physical world much better than your System 2 (and Newton’s), as illustrated by how much better humans are than robots.

Physics is both predictive *and* explanatory. Psychology is certainly not explanatory (concerning physical phenomena). Humans swim without knowing Archimeds' principle, play tennis and billiards without knowing Newton's laws, built airplanes before they understood why they fly.

And that a brain is essentially a prediction machine is quite a mainstream view in modern neuroscience, as I am sure you are well aware of.

So what? Same is true in physics (“Shut up and calculate”). And again, irrelevant to my point, which has nothing to do with the System 2 notion of explanation.
