Artificial neural nets are pretty far from brains. We don’t use them because they are like brains, we use them because they can approximate arbitrary functions given sufficient data. In other words, they work.

For what it’s worth, people are also pretty bad at math compared to calculators. We are slow and error prone. That’s ok.

What I was (poorly) trying to say is that I don’t care if the neural net solves the problem if it can outsource it to a calculator. People do the same thing. What is important is reliably accomplishing the goal.
