Only briefly skimmed, but don't you need nonlinearity for these things to work (e.g., rectifier, sigmoid...)? Else, it's just linear algebra, and more layers can't help (since matrices can be multiplied, the dimensionality is the only thing that matters). I don't think you can really get nonlinearity with one bit.
Not my field, so I'm sure I'm missing something. If anyone wants to ELI5 though...
I just say my name is Bigus Dickus whenever they call me. They usually hang up or insult me.
For the "car's extended warranty" I just tell them it's a 1969 Wayne Industries Batmobile. They usually just say they don't provide coverage for that car and hang up.
