alright big guy i'll bite. you're just generalizing an entire genre and demeaning it to being simple and linear which makes it "lazy" when i could do the same exact thing with pop punk, indie rock, pop, etc.
you can point to any genre and say "these acts make simple music, its a lazy genre" when in reality there are acts in all genres pushing boundaries and actually doing good things. you mention Tiesto, who in recent years has put out some pretty bad shit but his albums from the early 00's took EDM to new levels.
you can't pin point one genre as being more lazy than others. it just doesn't work like that. the fact that there are no lyrics to match to music doesnt make it lazier. there are more things that go into EDM than other traditional, organic styles of music and vice versa.
