There is a split ortholinear keyboard which looks pretty similar to this one: https://www.zsa.io/moonlander/
The Moonlander I really _want_ to get along with. It has an almost but not quite perfect setup for Emacs, for example, with natural places for Ctrl and Alt, and the software and configurability is excellent. I’ll likely give it a few more months but honestly if you haven’t got pain to deal with I don’t think these fancy layouts are useful, and even then I’m not sure my joints are any happier.
Only downside is the palm rest is huge, so you need a fair amount of desk space to use it.
