Watching today’s Veritasium:

The Trillion Dollar Equation

..

Reminds me of some acquaintances back in the late 1980’s who had started to delve into neural nets (then a new thing, as far as computers) to take advantage of the non-efficient stock market.

The video touches on some of the mathematics, which by itself is not too over-the-top for someone who has had a calculus class, but the implications are far more profound.

The entire ideas of randomness and efficiency when applied to groups of humans, as in a “market”, calls into question beliefs about ourselves as free-will actors.

Somehow we can act individually as though we have free will, but in the big picture we are part of a group that will manifest itself according to physics as described by math.
