I don't think fame has anything to do with it, but for what it's worth, I've been using emacs for over 25 years and have never suffered from any form os RSI.

I don't feel crippled, by the way. But since I like keeping an open mind, if you have any actual arguments, please feel free to share.

In the mean time, if you're also open, I recommend checking out some counter arguments, for instance in the work of Larry Tessler.
