"As for "speak for yourself", no, I was speaking for the younger artists that I know up here in Scotland: many very knowledgeable about what they are doing/singing/playing, and average 40 years younger than me."

And even, we ourselves, know much more than we did 40 years ago. Although there were a minority of very knowledgeable individuals and(even by the standards of those days) excellent musicians, most people were still finding their way including even the Gaughans, Carthys and so on.

In general, today's younger musicians are indeed more knowledgeable and "technically advanced" in musical terms. That's not to suggest that they will necessarily have the same "soul" or "feel" for their music or are as likely to be as ground breaking as many of the acts during the revival. Many of them will, of course, but some others might just take all the extra advantages and opportunities for granted. Only time will tell.
