Application software should be built using components inspired by Apple's OpenDoc project. The system should be an object system inspired by Smalltalk or CLOS that enables pervasive programmability of the environment and supports an objects-all-the-way-down environment, and the operating system should provide a REPL for programmers. The difficult part will be how to make such an operating system happen, since building an operating system is a large effort, and I believe part of the reason why the desktop computing situation in 2019 is the way that it is has to do with market forces. This is exactly right.
