Don't have the chance to watch the video but highly disagree with the title.

Math as a language is just a DSL which carries a lot of historical burden that is not friendly at all. Programming languages can achieve same level of abstraction with more clarity. Math instead added too much specific syntactic sugar(bad is multiply(b, a, d), log a is log(10, a) or log(e, a)), operator overload (/ for divide and dy/dx for differentiation operator, same grammar for scalar and matrix multiplication, one of which is communicative while the other is not), and complicated design (integral would be much clearer if we write integrate(target=ax, over=x, from=0, to=10) instead of the original one).
