Rob's hair loss sure seems to be in the intermediate-advanced stage...
-2 points for use of the term "non-binary" in this context, even though he's correct in his point, the choice of words was a ....choice, lol
I'm a bit surprised that seemingly so many people don't know the difference between playing abilities and instrument ownership, that Rob felt the need to create this video to show us the difference in the first place.
According to his video, I'd call myself an advanced guitarist, but in real life I don't feel comfortable calling myself that at all! Sure, I have a
particular set of skills...

....which I am very adept at. I have used these skills to create something of my own that sounds like me. I guess this makes me advanced?
Ask me to play some claw hammer banjo style licks on a guitar though? I've no clue. Sure, I understand the mechanics and they why's and the how's, but I am going to sound like the
beginner I am in that regard, because I absolutely would be.
I agree with the overall message of Rob's video here, though I think it's a little more complex than he makes it sound. Certainly not a simple binary concept, much more multi-faceted than that.
Absolutely nobody would claim that SRV was a beginner, quite the opposite. However, I can imagine listening to him try to learn to play something like Holy Wars...the Punishment Due....and suddenly he's much more beginner than master.
A truly advanced player likely won't refer to himself as such, because he's advanced enough to know that there's always something there to
begin learning.
Or maybe I've had one too many bong hits this morning, idunno
