I know plenty of people to took so-called 'hard' subjects like Maths, Physics and Chemistry who now work in McDonalds. You cannot determine someone's future success by their choice in subjects. Like said above, he very well may be the next Walt Disney. And even if you aren't, yes it does sound like you're bashing him, or at least being very judgemental. Taking an art's subject is not 'soft' and it is stupid to suggest so.
