I tend to think that peeps that criticize a young player that obviously practices alot, and say things like, "they don't play with feel, etc." normally aren't that good themselves. They have a delusion that just because they are playing slow, and making a funny face, that they have some magical, soulful, deep, feeling that no one else could even come close to understanding.
Being "soulful," or playing with feeling and dynamics, does tend to come with age, but players have to start somewhere. Having good technical chops and dexterity, isn't a bad place to begin. I wish that I wasn't so lazy when I was younger, and spent more time on technique. I think I play with feel, (feel is just as subjective as "tone" IMO) but I don't have near the speed or dexterity of some of the younger players, and I wish I did sometimes.
I say hats off to them, and hopefully they will write some cool music when they get older. To me writing is the most important thing that I look for as a listener.
