It's funny that most of these super hyped up mechanical keyboards still use traditional staggered non-split layout that will still contribute to developing RSI sooner or later.
I feel bad for the shoulders and hands of all those geeks using their tiny $600 cramped keyboards.
Any keyboard that does not separate into two independent halves (like ErgoDox or Matias ErgoPro) is horrible for posture and ergonomics.
https://shop.keyboard.io/products/model-01-keyboard is my keyboard of choice for most tasks, and certainly for typing. It's both split and ortholinear. It uses Mathias Quiet Click switches and custom-formed keycaps for the design.
