OpenAI and these companies do nothing of the sort.

Yes, they absolutely do and this is an example of it.

I would advise actually clicking through to see who the speaker is, who is categorically not a new grad nor someone with no experience in this domain.

I don't want to single anyone out but if you think this is "expert" level experience you don't have the relevant experience yourself.

I actually don't want to be overly critical but I do find the arrogance of these companies annoying.

Based on your replies I have zero reason to believe you know any better at all, considering the false statements you've already made (trivially proven, no less!) and lack of any meaningful critique of the source material.
