I didn’t say outpace, but I do believe the collective nature of open source will allow it to catch up, much like it did with browser tech, and at which point you’ll see a shift of resources toward that by major companies. It’s a collective works thing. I think it also is attractive to work on in open source, much like Linux or web browsers (hence the comparison to one) and that will also help it along over time.

I stick by my general thesis that OSS will eventually catch up or the gap will be so small only frontier applications will benefit from using the most advanced models

They didn't say "outpace", they said "catch up to good enough levels".
