I appreciate your perspective, and having thought about it for a few hours I find that I disagree. Windows, MacOS, Linux, etc. as operating systems are within the same domain of users; power user differentiation is currently a difference of preference, not of class or kind.

For other technologies, defaulting to open and targeting power users (and encouraging reasonable onboard skilling) is how we target all other tools, such as vehicles, power tools, and so forth that are used with a craft. Tradesfolks know their tools, and their most important tools they know enough to modify to suit their needs.
