The absolutism of some of their statements when we have 30 years of GPU research at our disposal is pretty eye-opening. I get that maybe this stuff didn't exist as a crate for rust but c'mon! Splines and shapes, glyph rendering, I wrote a game engine in C# back in 2007 that did all these things, and more. I like the explanation and the breakdown of SDFs for primitives but they are standing on the shoulders of giants and act like they're on an island.
