This is slightly off topic, but does anyone else think that the accompanying video is AI?

When I came across their twitter post about this, I was a bit taken aback. I think it is AI, but I can't tell that easily. I've seen Dalton and Michael videos so the facial expressions and cadence are off, but maybe I'm just seeing things? Anyway, no judgement on the use of AI or anything, just wondering if I'm correct.
