I had an interesting experience the other day. I have been using split keyboards for years, but only recently began using a Kinesis Advantage 360 Pro as my daily driver for work; I am so use to the layout now, that in instances where I have to use a non-split, or even my older splits, my fingers fail me entirely - like my brain forgot how to type, my thumbs eagerly searching for the thumb cluster that isn’t there.
I can switch between split and traditional row staggered (if the row staggered board is not a mechanical keyboard. Apparently my muscle memory for row staggered mechanical keyboards is messed up)
But I don’t like to use a „normal“ keyboard. Everything feels far apart and only reachable by weird hand motions. I got used to having everything in reach thanks to layers
