I think this is a good idea for a series. Although I think more detail needs to be given on the actual path, that is after all the purpose of the series. Most of this article seemed to be describing what NLP is and why it's hard. This isn't bad and some attention should be given to it but people looking to find the path into NLP will already be familiar with most of this information. I was expecting a bit more of a syllabus type format. There was mention of needing some college level algebra and statics, I would have liked more detail in this area with links to more resources (classes, articles, datasets, etc). Keep up the good work!
