I don't know, I think the learning curve is pretty gentle. Like all complex software, it may be difficult to master, but getting started felt easy enough as far as I remember.

I found it incredibly frustrating at first, so much so that a Loupedeck became a wise and necessary investment to keep the anticipation of editing burden from beginning to depress my interest in photography.

I still have the Loupedeck, on one of the shelves behind my desk. I think I might have used it twice last year.
