I think the point here is that he has some really spicy takes that one can not call balanced or objective by any measure, while not doing anything that's impressive enough to actually deserve to be taken seriously when it comes to such sweeping claims.
He was a programmer at RAD game tools, which is industry standard for game tools. He also was the principal game engine engineer on The Witness, and has probably worked on other 3d games in the industry.
Is that true? He is listed in the credits under "Additional contributions in programming by", and in his blog posts about the "Walk Monster" problem, his role sounds like that of an independent contractor brought on late in the project.
I remember he mentioned something about his role to that effect in one of his handmade hero streams. Can't remember which exactly, but he did mention he did a bunch of code contributions to the engine. Possible I am misremembering.
In any case, he has experience in working on and shipping actual 3D game engine code.
>Having looked at UE5's promotional content, I'm honestly just wondering: what is the point of Unity, now? Either you don't want to deal with a big unwieldy engine, in which case you roll/mod your own, or you do, and you would just use UE5, right? What am I missing?
>It seems like it is so far ahead of Unity at this point on all fronts, including asset provision (megascans + metahuman), I'm honestly just not sure what Unity's value proposition would be. Maybe devs who are sticking with Unity could fill me in?
Maybe he was truly just curious on an engine he never worked in and was genuinely impressed with the car sticker UE5 was showing (another engine he almost never worked in, so getting the information purely from PR. Point for Epic's PR team). But anyone who's seen the "debates" on those engines know he just sparked another war.
Casey has been in the industry since before DirectX existed, worked for RAD Game Tools, and likely has code in more games than you've ever even played.
...and I've been programming games since 0x13h ModeX and contributed to core industry software. Which means absolutely nothing. It's quality times quantity. Not time and acquired credentials.
Well then, perhaps you have inside knowledge to share that justifies your claim that Casey hasn't done anything "impressive" enough to justify his take?
