As someone who did contribute to NLTK quite a bit, it was quite useful back in the day especially when I had to teach NLP&#x2F;CL to linguistics (non-CS) graduate students. I agree with Radim that NLTK has a purpose - and it&#x27;s not to implement the latest and the greatest NLP algorithms. I&#x27;m glad NLTK exists and although it is not what I use today, I&#x27;m pretty sure whatever I do use today (CoreNLP, gensim, etc.) will all be superseded by the next best thing a decade from now.
