I've tried a few times but given up each time. I learned to touch type QWERTY at age 13 and use it at well over 100wpm. I'm in my early 30s and I think I'm stuck with it now.

Even after living in Germany for ~10 years, I still buy and import US keyboards and laptops so that the enter key (and backslash) are in the right place. (It's not just mapping - the physical buttons are laid out differently.)

I read about these people who switched and it seems totally impossible to me. Months of slow typing?! Ain't nobody got time for that.

I'm pretty much in the same situation, after 20+ years on QWERTZ (German here ;) ), I can't even imagine using a layout that's so different. I already go borderline crazy when some programs/games change the layout to US QWERTY and a dozen or so keys stop doing what they're supposed to do.

Imho it's nearly impossible to retrain decades of muscle memory and end up with the same efficiency/speed without spending a comparable amount of time to train muscle memories on the new layout. Sadly we humans only have a limited lifespan, so I rather stick to what I know and already good at.
