Not only afraid of math. Afraid of math and at the same time confident that one will excel with deep learning.

Lots of people make use of relational databases without formally understanding set theory/normal forms. They just learn by example and hacking it. What you're seeing here with deep learning is the same situation.

Sure. And I didn't at all mean that people who aren't good at math should stop doing deep learning.

I just meant that it's weird to me that people seemingly tiptoe around using simple math to explain what is, at heart, simple math, and instead invent a whole new terminology and a dictionary of imprecise analogies to get by.
