Easy take: calling linear algebra “quantum physics” and “artificial intelligence” is hype. Deeper: the huge influx of physicists into AI has produced an intellectual monoculture that isn’t capable of addressing key problems in the field.https://twitter.com/WIRED/status/1181437300414275584 …

I mean... the whole thing looks like physics to me? You’re shaking a ball on an energy surface.
Minimizing a cost function using SGD/backprop is like physics in much the same way as eigenvectors are part of quantum mechanics.

It occurs to me that I don't know where the theory of mathematical optimization (& notions like objective function, gradient descent) comes from. Certainly, it was buzzing as a subject independent of physics by the 1950s. But its roots may be in part in physics, earlier.

One major strand in the history would be cybernetics/control theory, which was applied physics initially—the radar-controlled antiaircraft gun being the paradigm for the field
