@NOTimothyLottes They design one API for each separate use case instead of making general purpose flexible SIMD hardware and API for the developers to implement what ever algorithm they need.

I kind of understand hardware T&L back then because it was a new field and programmable hardware didn’t exist. But now we have massive amount of wide SIMDs and bandwidth and big caches too. We can do better!
