If you know about a topic well, his videos are not as accurate as he may try to make you believe

That’s a good point, he did a video in my space recently and while it sounded impressive it was clear he only had a surface level understanding of the domain. Still impressive, but I find it hard to trust folks that represent themselves as experts on topics they’re not really experts in.

When does he represent himself as an expert?

He's fairly transparently doing the work of what you'd perhaps call a 'pop sci journalist' or so.

Do you mind sharing which specific video it was?

He probably has a team who helps him. He makes bank so not unrealistic

I think he still has a dayjob actually, or at least until recently. So I'm not sure wether he has staff.

he's started making videos way before LLMs were able to aid in researching content. He's just good at doing what he does, no tricks there.
