The speaker says hardware co-optimizes around successful approaches, making new ideas harder to pursue when they are a poor fit for the hardware.

“people were doing just crazy fun stuff and now it's really narrowed in and and part of it there's like also a bit of a hardware lottery kind of thing because once something starts working the hardware also starts co-optimizing against it and so it's harder to find even if you have a great new idea if it's not really a good fit for the hardware you know it doesn't make sense so to answer your question”
