I agree with you mostly. I just think that this is an interesting usage of variational calculus, which is not that well understood by other programmers, so I wanted to write this article about this, in order to introduce other programmers to the topic.

And also because I thought the literature about this out there wasn't really that readable, and I always think there is value in writing expository texts like this.

Yea I really liked your post because of that focus. I use variation all calculus quite a lot for non-programming stuff and it’s really allowed me to understand things like NNs way better and I think so many other programmers could benefit from a small bit of it.
