There was a (somewhat) similar interview of the Pinçon-Charlot recently in la-bas.org, you have to pay to access it though. I didn't linked it.
The ideas defended by Chomsky here aren't new (to people following his work), but in these times I think they give quite a remarkable insight on what's happening.
The main issue has I see it is that all API functions accepts only XML as content-type. There is no way to use JSON, which is rather standard by now. Even GET serves only XML.
Another issue is that the error messages for non-conform requests are not informative enough. This is emphasize in the doc ("unfortunately error messages are not consistent").
Finally, in my opinion, the doc do not provide simple and clear overview of the API.
Very impressive, I was thinking at first that you used deep learning. According to the website, you discarded this approach because of the lack of interpretability in deep learning.
Although it seems to me that high dimensional data, while not being black box, are very hard to interpret as well. Could you give an illustration of the interpretation process you are using?
I am also curious about the construction of your training dataset. Did you used some existing pre-labelled reference data or did you build it by hand?
That's a good point, the plethora of frameworks is actually a burden for front-end dev. Moreover the building process of moderns web-app is also a jungle (webpack, rollup, browserify, npm...).
Getting started as a front-end dev can easily lead to choice paralysis about framework as well as tutorial hell about building process.
On the other hand, mastering the fundamentals of JS isn't very fun in itself. It requires lot of dry reading with few practical examples, if you have few experience these examples are difficult to contextualize.
It may be more effective to pick one of the big three (Vue, Angular, React) and get your hands into it by building some fun stuff. Once you'll have practical knowledge, you'll have a better idea on what aspect of the fundamentals are worth digging.
