Life is gradient descent

Recently, I've been learning about Gradient Descent. It's a really beautiful algorithm that helps find the optimal solution to a function, and forms the foundations of how we train intelligent systems today. It's based off a very simple idea -- rather than figuring out the best solution to a problem immediately, it guesses an initial solution and steps it in a direction that's closer to a better solution. The algorithm is to repeat this procedure, until the solution is good enough. My theory is that this is the way we humans work.
