I think you might be reading too much into what is a lighthearted video on YouTube.
That's so true, and as I grow I'm trying to break social barriers/shields (being more open/authentic/personnal immediately) more and more with unknown people: it just makes relating to people much more enjoyable and profound! It's not even about the hypothetical profit you could get.
I think this is more along the lines of what he was trying to say; he was young and dumb and now he has learned from his mistakes.
One interpretation of this guy's video is that he recommends befriending nerds on the basis of potential material gain. Another interpretation is he applies this standard to everyone and only recently realized nerds can conceivably meet it too. Still, pretty funny vid.
before getting to know them.. but then you should.
