This is a lie and most of us know it. AI companies have been lying and lying and lying and lying. If you believe this then the AI companies have successfully lied to you and are making you pay money for an inferior product. If this weren’t a lie then the AI companies should have the research to prove it, they have not, because it is not true. AI does not help anybody learn anything better then using traditional methods.

So my personal experience apparently is a folly that requires some bureaucratically approved scientific study to validate?

Yes, it is well known that people trying to sell you stuff lie about your experience with the product. A good salesmen will make you extremely happy to pay 10x more for a worse product. In fact a good salesman will convince you those bugs are actually feature, and you should be happy to pay 10x for so many “features”.

What exactly am I selling here?
