It seems like this mostly focuses on ergonomics as the next dimension of improvement, but there are several other factors that come: Manufacturability improvements could reduce the cost and make customized solutions cheaper and more accessible. Repairability improvements could extend the life of keyboards and add options for improvement over time. Recycling would be nice to consider since most keyboards quickly become a lump of mostly plastic e-waste that would be good to systematically melt down and reuse or at least dispose of safely. And perhaps most obvious with the pandemic is sanitation. Most existing keyboards are not easy to clean, may or may not survive a trip through a dishwasher, and protective covers tend to mess up the ergonomics and are not necessarily built for cleaning or long life themselves.
