It's essentially the classic Smalltalk workstation model. End user programming, where the user live in a live easy to bend environment and just have to write few bits, some listings, to bend the desktop to it's wish. You are in a MUA composition windows and want to solve an equation? You have some bits that do so in your system, no need to switch "application", just feed the input to the relevant function and get locally the result. You just want to change something? Easy to do, it's just few bits of code. This is the most effective and powerful use of a computer we have ever invented. It was dropped because no one who works in sw business want power users and easy to bend code, it's nature is collaborative, not commercial. It's nature allow people to understand and those who became "alphabets" do not like Alphabet's or Oracle's o Meta-information business and they can perfectly goes on without them.
