never seen lex so adamant about his view point he's really a bit stubborn lol, even choosing to end the clip with the last word.  Everyone's entitled to their own opinion, but the argument ends up turning into both putting their foot down lex saying its difficult and complicated and jk saying its simple and solvable.  Think its definitely propogated by Lex tho, rather than just keep reiterating that its hard to predict human capabilities he could have gone into some clear examples that proved his point to create an actual unbiased and perhaps less emotionally charged debate
