I think that most of this comes from the gross oversimplification of all of this. The points made about growth mindset are good: talent is important, but effort is important, and you need BOTH. Not just one. The problem is a lot of people, at least in Carol Dweck's world,apparently don't realize the value of hard work -- hence growth mindset. The problem arises when people decided hard work is ALL of it, not PART of it. Let's face, not everyone is capable of everything. I think it's just as important for kids to learn and appreciate that there are some things they are not capable of as it to realize there are things they're capable of. Telling kids they can do anything is a nice, happy-feeling solution in the short term, but it's hurting them even more than a fixed mindset. I mean, I'll never be an artist either, but I can understand that and appreciate the effort on the part of those who can and the beauty of what they create, and that's important.
