I don't get it either, because that has always been the case, thus most of his post is borderline non sense.

Yes, making software development cheaper has been the main priority of the industry for a long time. The new development is that there's now a magic "do what I want" button that obviously won't quite do what you want but it's so cheap (for corporations, not humanity...) that you might as well pretend it does. (Compared to paying professionals who might even care about doing a good job, that is.)
What's funny, is some will say, "use the app" instead for things like this... why should I trust someone to build a safe/secure app, who cannot build a reasonably functional website?
If your argument is still that you don't want to trust a company that can't make both functional, well... maybe you shouldn't be going to Jack-In-The-Box in the first place.
I don't actually install that many apps, and generally not retail apps anyway.
He explained the reasons he went into the academia, which is because of the AI, and AI is not the reason he stopped with development.
