I do kind of think the solution to this issue lies at the OS level. It should provide a high degree of UI and workflow standardization (via first party apps, libraries and guidelines). Obviously it's an incredibly high bar to meet for volunteer efforts, but the user experience starts at the OS level. Instead of even installing a program like "Handbrake" or "Magicbrake" the OS should have a program called "Video Converter" which does what it says on the tin. There should also be a small on-device model which can parse commands like: "Convert a video so it can play on facebook" and deep link into the Video Converter app with the proper settings. Application-level branding should also basically not exist, it's too much noise. The user should have complete control over theming and typography. There has to be a standard interaction paradigm like the classic menubar but updated for modern needs. We need a sane discoverable default shell language with commands that map to GUI functionality within apps, and the user should never be troubled with the eccentricities of 1970s teletype machines.
