It didn't. I ultimately read it as a comment directed at Scorsese.
I agree with you a great deal. The commercial film has largely been 'solved' - to borrow a term from the AI field - in a great part due to the factory-farm methods of bank-driven modern Hollywood that Scorsese is decrying (sorry).
This lady has a theory that there are roughly three types of creativity which then mix: exploratory, combination, and transformational. Hollywood's been running on the second type for quite a while and it's been kicked into absolutely st00pid territory since around the time mentioned earlier (2005-ish)
Also, in case you didn't know, the film is often likened to a poem and TV to prose. This has been a huge factor in the rise of TV/streaming shows and the mass exodus of writing talent away from film and towards the more long form of serialized shows, particularly because of the amount of creative control they retain in the latter and the lack of 'space constraints' that really hamper a writer in the former. That (along with the big-screen home system you pointed out) has also been a factor in the slow strangulation of commercial film - literally all the top talent ain't that keen on writing movies anymore.
I really like that meta-analysis of JP.
P.S. I'm pretty sure I'm preaching to the choir here, but the real top writers do try quite hard to add some layers on top of 'the skin'. Silence of the Lambs is the descent of two women - one victim and one agent (in the non-vernacular usages of the terms) - into the hell of a world designed for and controlled by men. JP (the film) is the idea of "family" faced with the age of genetic manipulation (the book is about a favorite Crichton theme: the illusion of forethought in the technology sector). Mad Max: Fury Road wasn't nominated for an Oscar for no reason, even if the reason is tres meh: it's a road movie with the dad and mom switched and that new family dynamic ultimately overthrowing the old patriarchy.
I guess the point I'm trying to make is that there are/have been people who are aware of the problem and who are doing/did their best to try and keep things churning, even if like you point out it really doesn't stand up to much scrutiny.
