    It is nice to compare your product with others, but it is not nice to dump on open source projects. In python students really learn machine learning (and deep learning) being open source, code is workable and understandable and one can learn by changing a lot of things, this can't be said for Mathematica that abstracts everything, also, if abstraction is required (easy and faster development) then keras for tensorflow and lightening for pytorch are good choice. I love mathematica, and I love mathematica for easy math syntax and graphics, I think they are the best (and easy, compared to any open source language) but since mathematica is closed source I don't really understand it much, I only use it for mathematics and graphing equations or system of equations (or simulations with systemmodeler).

    BRAVO!!! I would highligth the "compiling the compiler" advance. And also the tech advancing process of "compiling a function and then injecting into wolfram interface" for using while coding, This resembles very well what natural physics and natural life forms are doing: Working by the dynamics of "second order differential equations". We, as humanity, are going exactly trough that process in an umprecedented threshold with AI, Now, as we work so tightly with it bettering it and also bettering human though (trough NeuraLevels neuroservices, for example), we have entered the Hybrid Artificial Intelligence Era, and it is a "second order differential equation" type of process, just as Mr. McLoone presented. We have hopes... and now all the tools needed to do it GREAT!

    The big problem is that even if Wolfram can do something, chatGPT often can't figure out the right syntax to do it. Probably there were not nearly enough samples in the training data so that it knows how to correctly interact with Wolfram Alpha / Language. Simple example: "Give me a bar chart of the 10 most valuable currencies in the world." It fails. If you instead use the browsing mode and ask: "Generate Python code for a bar chart of the 10 most valuable currencies in the world." you get exactly what you want. Also, I feel like some of the data in Wolfram are really out of date like month-over-month inflation data hasn't been updated in over a year, as far as I can see. This is very old compared to data you can get through a simple Google search nowadays. So it is really not clear to me if data is a strength of Wolfram, compared to all of the internet that chatGPT can access with the browsing mode.
