Uh. You do realize his use of spandex was a metaphor, right? His argument was that you can't future-tech future tech. Something that became rather evident early on in TNG's run and was abundantly clear by the end of Voyager. In other words, the spandex had become increasingly tighter to the point - in the most extreme case - was literally suffocating. Yet, relatively speaking, the future was functionally and practically identical. The spandex was his metaphor for the pretense of it all. After the mistakes of Disco, it seems Kurtzman has learned that same lesson, as the wearer of said spandex now appears in something akin to what I might wear to a market run. And Burnham is wearing something akin to what I might wear to a market run in December.
