Your reasoning is not wrong, there is a neural net that approximates future stock price. The problem is we don’t know which one :)

- dzaima 5y agoAnd knowing which one it is will probably influence which one it should be, in a halting-problem-esque way.
- vimacs2 5y agoSo it's somewhat akin to the Library of Babel but instead of the set of all possible books, it's the set of all possible functions :p
- hedora 5y agoThose are equivalent as long as you allow for infinite length books.
- Banana699 5y agoNo need for infinite-length books to encode all possible functions, as there are notations to express infinity in finite space (e.g. programs, encoding an infinity of behaviour in a finite number of instructions). The library of babel contain every possible finite description of every possible function.
- hedora 5y agoSure we do. Partition your neurons into a few billion independent networks, embed them on a spinning globe of mostly molten rock, and put each one in a leaky bag of mostly water. Wait long enough, and one leaky bag will emit the number "42". If you get the initial conditions just right (and quantum nondeterminism isn't really a thing), then you'll also get a good approximation to the stock market.
