I read that whole (single) paragraph as “I made really, really, really sure I didn’t violate any NDAs by doing these things to confirm everything had a public source”

I was lost when it suddenly jumped from a long retrospective on GPUs to abruptly talking about "my allocator API" on the next paragraph with no segue or justification.

You only read two paragraphs in then?

haha, instead of making them read an AI-coauthored blog post, which obviously, they didn't do, he could have asked them interesting questions like, "Do better graphics make better games?" or "If you could change anything about the platforms' technology, what would it be?"
