With the development of tools of video production, perhaps one should figure out a new ecosystem of creator driven (as opposed to moneyman) productions, especially with the fading importance of actors, real sets or animators. Makoto Shinkai made Voices of a Distant Star by himself after all. (and subsequently grew into Your Name at highest grossing anime film) ....Or perhaps that is how it has always have worked, see how Hidaki Anno started out with Daicon.
From a general systems theory perspective, it is more feasible to grow a small success than to improve a large failure.
This is a common fantasy. The "fading importance" of actors and animators? Not so. Respectfully, just wishful thinking. Highly skilled people need time to become highly skilled at what they do. The internet has wrongly influenced some into thinking that *anyone* can do anything in 5 minutes. It's just not possible.
When someone sees someone else's work, and find out they did it themselves - it must be easy also? Not true.
What I am saying that talented and motivated can produce a workable product mostly by themselves with improved tools. What I am not saying is that any one can do it. What this means is reduce barrier to entry by the said capable people born in the wrong place without the right friends. Now small scale projects are indeed limited in many ways, but can generate products of sufficient quality especially when aimed a narrow niches which is growing as fraction of media consumed.
Fourth season, the suits lost interest and turned the show over to fanboys... and the fourth season was awesome.
From my perspective, you are probably not deep within some fandoms.
Strong Fans are not normal people. They don't have much life experience, is not top tier in imagination and is abnormally obsessive. Entire genres and franchises taken over by its own fans grow ever more obscure and weird (from an outside perspective). Medias become increasingly self referential will the implicit assumption that the viewer has consumed hundreds of hours of other related materials to understand the context.
The end point is in jokes and 4th wall games together with narrative that does not make sense in a stand alone story but one that makes sense in the insular meta scale.
Now as an animeposter, I have seen how an 'artform' have evolve outside the normie space. Entire shows about cramming in jokes from other stories and nothing else. Entire show not about organic stories (like hero's journey, growth, relationships) but about manipulating story elements like with things like "fake rival character gets shipped off", "prequal main character steal the main char role 'drama'", "make the self insert char the villain", "Classical ship wars pwnt by out of nowhere 4th option~", "play the 'wrong BGM' for events" and so on.
The core of escapist fantasy enjoyers also lead story down strange path that could not be pursued by "normal" people. There are franchise of planetary war taken over to serve as backdrop for homosexual 'romance.' There are characters whose defining feature is as absurd as "having infinite money, with an AI to spend money faster" with an money spent tally shown at the end of each episode. Oh then there is 'settling' sperg debates over 'vehicle A is better than vehicle B' by means of writing the sequel or the supplementary material.
There is no bottom to arbitrary measured 'quality' that people will make and consume, there is only size of addressable demographic, exhaustion of novelty and "whose porn is this for."

You need someone with greater independence then either fans or suits for true, broad reaching stories.
How is he wrong to point out how in old Trek there was clearly a respect for the chain of command and proper bridge decorum, while in STD it's pure chaos?
The error is thinking that chaos is a bad thing, as opposed to identifying who is it that want this? Given that people still watch it, some people may not mind or event want this.
People generally do not watch to learn how things work, there are vastly better ways for that. Instead people watch for emotional payoff. From personal introspection, watching incompetence is fun as "tool for self rationalization of displaced feeling of hatred." Just pattern match those you don't like with buffoons on the screen and you feel better about the jealousy.
