At this point I'm pretty terrible at QWERTY on a physical keyboard. I'm fine with it on phones and tablets for some reason, but my brain is pretty hard-wired for Colemak on physical keyboards at this point. I also use a Kinesis Advantage keyboard which adds to the context switch when I have to use a different computer (though this is less significant for sure).

If it's a Mac, Colemak is one of the pre-installed layouts, so if I need to work on someone else's computer I'll just enable it while I work on it and remove it afterwards. Otherwise I can manage, but it does slow me down quite a bit, and I'll have to look down at my hands pretty frequently. You immediately notice the extra workload though: Colemak is pretty low effort, but QWERTY just feels like finger moshing to me now.

I'm pretty sure it's possible to remain proficient in both, but QWERTY was sufficiently destructive to my hands that I use it as little as possible.
