I don't know anything about music, but I feel this debate is like guitar tabs vs. standard music notation. I've heard, for example, that Paul McCartney doesn't know how to read music notation. "Yesterday" is still a masterpiece, though. Now imagine if Paul all his life advocated young musicians against musical notation, because "It's hard to learn to read it. And it's overrated."
The truth is - Lisp is fundamental and absolutely essential for anyone who chose a lifetime career in computer science. And it's not going anywhere, anytime soon. So please stop whining about it and at least get yourself familiar with it or stop calling yourself "a pro."
[Apologies for dramatization, the last part is not aimed at you personally. it's a general message for everyone.]
I'd like to see a university test this theory. I suspect it's subjective and varies greatly per individual, but testing on say 100 random subjects could better resolve the Great Lisp Dispute.
