Have fun pulling notes from websites without ML. NLP just plain didn't work before ML. The thing is that with ML you are able to work with unstructured data, e.g. routing email without having a complicated system the person mailing you has to understand or hundreds of brittle, hand written rules that in the end won't fire anyway because somebody spelled a word wrong.

I think ML/AI is just not ready for a lot of applications because it's not good enough, but our models are still improving every month. Impossible to know what it's like in 5 years.
