I do agree with you. But imagine when you've become the person with 5years experience - then i doubt you'd be against it?
Then again, 5years is crazy. I reckon you learn 95% of a language you'd actually use in the job in the first 6-12months. Thereafter you'll just pick up little snippets here and there to help out.
I'm currently at about 4 years experience and I still think its bogus. As you said, 95% of the stuff I need for the job, I'll learn in 6 months.
