Not to be that guy, but techno is only repetitive if you are a) listening to boring/uninspired techno (the same kind of complaint being leveled here against HAA), or b) not paying attention.
"in a way that feels tiresome" is the operative phrase here. I like the throwaway tracks on Homework that are twice as long and half as interesting more than I like most of Human After All. They're fun.
Being robotic and repeatitive never stopped people dancing like crazy to techno all night. In fact, that's its very allure.
