There are many great guitarists who have never reached Mr. Claptons level of fame. I live near DC, which spawned some of the best: Roy Buchanan, Danny Gatton, (both deceased-seen them both), Link Wray, Tom Principato (still performing). Then there is Larry Carlton, Walter Becker. Many others who never rang the top 40 bell.
Great list of guitar players but Gatton, Roy and the others are not really considered by me to be Rock Guitarists. Clapton could never play like Gatton like most of us cannot. But to your point there are many great guitar players still playing today.
I do not feel that Eric sold out - hey you get tired of playing your hits songs over and over again. Enjoy them while you can. It is also hard to be creative.
