Ironic that you mention material design and DO as prime examples of good UI when any UX designer who has to deal with the blunders of those two things will tell you that both are examples of horrible UX/UI.

I call this me-ism. Because I think it's good, it must be good. Because the company I like is doing it, it must be doing it right. What most people who gripe about design & UI do not seem to understand is that those decisions were made for a reason - usually to bring some sort of value to the table not for the sake of making things look clean and fresh.

Another comment here shows some ignorance too by saying that "I was lead to believe that its best to assume users are dumb, but my experience is on the contrary". This comment completely misses the point that users of one app/website will behave differently from users of another app/website and what works for one may not work for the other. At the end of the day there is a business being ran and money being made - the design decisions they make typically impacts their bottom line (for the better) or the design would have been reverted.
