For the first point - at least read what I wrote after the sentence you picked to quote, and try to address the example with unlocking the phone.

For the second point, read what I wrote before the sentence you picked to quote. Also, your not liking or accepting some result doesn't really change it.

This isn't how to argue in good faith, and it's overall not very productive for anyone involved.

Your example wasn't a good example. For starters, it's literally a binary decision to make (yes/no: is this jstx1 trying to unlock the phone?).

Most of the tough, interesting, challenging problems in this world don't boil down to binary decisions.

Second, facial recognition doesn't depend (inherently) on artificial intelligence. It's not a great example. It's not a truly interesting, tough problem. It's not in the realm of fuzzy logic, concurrency, periodic or aperiodic behavior, or nonlinear relationships.

Could a Neural Net do it faster? Yeah, sure, maybe. But so what? You have a quicker algorithm, a faster heuristic.

PaulHoule, on the other hand, gave a great example:

>For instance, where should a modern book on digital photography be filed in the library? Should it go in the 000's with computing? In the 700's under art? Or in the 600's with technology (an application of optics, electronics, etc.)

I don't how you expect a non-binary example when you've titled your own question "Sigmoid Functions & Binary Classification".
