Being a terminal purist is wonderful for those of us who live our lives deep in the caverns of Linux, but in actual production use you very often find situations where less technical users have to interact with the systems that we build.
For my work, I need a way for low level tech support and technicians to go in and restart a container from time to time, and these people curl up in a ball and scream if you show them a command prompt. Having a UI removes a lot of friction.
The problem is that a lot out economics relies on “models” that estimate the price of milk by assuming a frictionless cow on an infinite plane. There’s a distinct lack of attempts to actually test the models against reality, or simply study reality itself (the reason likely being that when people do study reality instead of models, the progressive economists most often turn out to be right)
