I mean, that's entirely possible, based on the one account we have from the showrunner, it could be interpreted as the show runner is being greedy and George just wants art made right, or it could be read as George obsesses over these boring little details that no one else actually cares about and needs a better editor.

My point was just that either way, this is how it was always going to go after Dan and Dave ruined the original series by rushing it. They're lack of care and attention to detail may have been the final nail in the coffin for George ever letting people substantively edit him again, regardless of whether or not it would be beneficial.

The lazy river book with Tyrion convinced me the GRRM's editor is actually a cat or dog.

And has totally stopped trying.
