That pyramids is “easy” is some dumb shyt said by a nikka who prolly can’t even build a dresser. It wasn’t no “alien” shyt like these crackas try to say to take credit away from black people but it damn sure wasn’t “easy” and it was far more complicated than “you just need enough people”. Especially given the tools they were working with at the time. Thing with Lupe is. He is very intelligent but he always thinks he’s the smartest nikka in the room. He buys into his own hype. And he’s a person who is able to lend his opinion without being challenged by true experts in the field he’s speaking on. If he sat in front of a person who extensively researched some of the shyt he says he would most likely hit a brick wall.
I've even seen him lose arguments to people on his IG live who aren't experts, but are well read. Lupe is one of those dudes that knows 99% of the people he comes across aren't well versed in the amount of topics he is, so he has the upper-hand in debating. But like you said, if he was to debate someone who's actually well studied in the topic at hand, a lot of the things he tries to get off, would be broken down easily.
Only thing Lupe does, that I do appreciate, is he debunks a lot of illogical conspiracy theories people throw out. He does it by using simple common sense. Outside of that, he's an obnoxious know-it-all.
