Re: A serious question.
Shadow Systems, imagine some trendy designer thought it would be "cleaner" or "cheaper" to just draw Braille dots rather than make them 3D. A "flat" UI isn't even in the same ballpark, but it's annoying and stupid regression. The ongoing increase in processing power makes it unnecessary.
Of course, on-screen 3D isn't really 3D but it does make buttons stand out better visually. I guess a temptation then is to make the button smaller and hence harder for people with shaky hands and weak vision to hit :-(
