Yes, because once you're older than 25, you start liking ancient forms of film (regardless of what you thought of them before), horrible superhero movies, and in general lose all of your personality and ability to get angry.
No. The older one gets, generally, the more one actually knows as a result of experience and therefore the more interesting one's point of view becomes.
Becoming less quickly and intensely angry over trivia is an aspect of maturity dearly to be hoped for.
If your tastes are the same when you're forty as they are now, you'll have failed at life. That said, I don't think there's a real likelihood that this will be the case.
