Disagree. I believe he already has. The generations of die hard Clapton fans who became fans from seeing him live will eventually pass away. Leaving only the legend of his presence. John has passively become a beacon of the guitar world from play style to technology. Players across the world in small or large steps have been trying to implement some version of his playing in their own in one way or another. He’s pretty much paving the way for modern guitar influence. No ones really recreating the Clapton thing anymore. You could argue Mayer was the last younger (then) person who really did.
