Ive seen this with young hopefuls. I seen one seize on the phrase 'You've got to show you want it' and not look past the literal meaning. I was told the same thing when I went for my karate dan grading. I understood that it meant demonstrating commitment. The commitment of course, must already be there.
There will always be individuals who will devote themselves wholeheartedly into their chosen art. However I think there will be far fewer of them from here on. How many people want to become good musicians, but lack the discipline to practice. Everything is becoming faster and easier, but there are no shortcuts to learning skills. Its not just about 'today's culture' though. In my teens I recall a fellow student remark that he wanted to be a major artist, but didn't want to spend 10 years getting there (WTF?!).
When someone speaks to me after a gig about playing guitar, there is a familiar theme. "Ive got a '(insert guitar model)' and I really want to play, but I dont have the time to practice". I usually say something like "well you have a life to lead, why be like us sad acts and spend hours fingering a piece of wood eh?".
But in point of fact I actually enjoy practicing. I dont have a routine, and usually have no idea what I'm going to do when I reach for the guitar, but always find something interesting before very long. Maybe that not practicing, but it serves the same purpose.
By now, the precedent is established, young people can see easily enough that there are celebrities that are well known for nothing. They have no special skill or talent. Just as everybody now wants to be on a stage. No one wants to be in the audience. So there is karaoke, and open mic sessions where grim faced singer/players take it in turn to get up & perform, but they dont listen to each other, and once they have performed, they leave!
We need much larger stages. We should just tear out the seats where the audience used to go.
