As a music educator, I disagree. What we're seeing in education right now is a majority (it used to be a minority) of students that lack GRIT, which is that stick-to-it mentality. For the current "crop" of K-12 students, things have to be immediately attainable or they abandon ship. This is particularly true if parents allow it. And many do! While I am sure that abandonment of guitar has always been large, 90% certainly reflects our current era.
And of course, there ARE exceptional kids today. Plenty of them. But the majority of the generation lack that skill of GRIT, and that is going to become apparent in the workplace over the next 10-15 years. Many businesses will tell you that they already see it!
The guitar is an interesting instrument. As it has been the primary instrument in pop music for 60 years, most people want to play it. I would even wager that a large number of people have tried. But it isn't a "super accessible" instrument where even this simplest progressions require three fingers on different chords on six strings (Key of G).
And guitar saturation isn't the issue...otherwise we wouldn't have Guitar Center and every other music store filled to the brim with guitars.
I applaud Fender, and Zivix (JamStik) and companies like UberChord and Yousician for trying to make the guitar more accessible.
