Great video! But the short answer is no.
Learning FCPX (and I have) is much moire like going from a Mouse to Wacom tablet (I’ve done that before too). Unlike the bicycle, people who learn a Wacom have no trouble going between a mouse and Wacom. Similarly, I have no problems going back to FCP legacy or Premiere – although i don’t find i ever need or want to.
Some said the question is “Is a backwards bicycle better?”. I don’t think that’s the question at all. That’s like asking if a Wacom is better than a Mouse. You gotta be more specific – better at what?
The bicycle example is much more analogous to apple’s “Natural Scrolling” feature. If i use a computer without that now I can barely drive it!
