I skimmed the lecture after first ten minutes and as far as I can tell, while it seemed like it would be interesting to someone interested in what Boston Dynamics was doing, it doesn't really say anything about AGI beyond "we eventually want to do AGI and we think doing robot stuff well will get us there." If there's something I missed, could someone say.

Since this is part of an MIT lecture series on AGI, I think the GP is sort-of justified in also asking where that part is.

that is a great quote, indeed that happens at all levels, sounds like a cover up for false modesty.

It's humblebrag's cousin - the shamebrag.
