I realize now that my first response only addresses how an individual might ideally decide whether to switch to Dvorak. Deciding which layout is “fitter” across the globe (or whichever language regions currently use QWERTY and can feasibly use Dvorak) is a much more difficult cost/benefit analysis in practice. To calculate cost, you would need to look at the costs of mass manufacturing new keyboards and/or patching and distributing the software that drives keyboard input. To calculate benefits, you would need to do large scale studies on the speed/productivity benefits of Dvorak over QWERTY, both for first-time learners and switchers. Heck, you’d even need to estimate the political costs (for governments, large corporations, standards bodies, etc.) of persuading the change, as well as the unavoidable costs of having both layouts exist in the wild during the transition period. This is so daunting that it feels nearly impossible, and indeed, I suspect any rigorous cost/benefit analysis would show that the benefits of any new layout (even the technically best layout) is not worth the costs of switching away from any single ubiquitous standard (even the technically worst layout imaginable), at least not in any reasonable time frame. My guess is that the best approach is to maintain one ubiquitous standard, and change it very gradually, and to gradually reduce the costs, e.g. by implementing easy layout-switching software in major operating systems, or even bolder approaches like supporting virtualization/containerization of personal software settings and development environments in major operating systems. What if I could just sit down at any modern networked PC, type in a URL and some authentication, and immediately be running my own exact customized computing/development environment, complete with my keyboard layout, text editor, development dependencies, etc.? That would be awesome. As long as the hardware keyboard layout is roughly compatible with my software settings (and I don’t rely on printed labels on the physical keyboard), most of the costs of choosing a keyboard layout (other than the fixed costs of learning it) go away. |
