The strange chicken and egg problem there is that- How do users know what they want to do with their computer unless they know what it can do?
Centralized platforms like Google, and Microsoft tell the user what they can do with their products. Linux distros allow the user to do anything they want but if the solution isn't prebuilt, the user has to build it.
This is literally the premise of the rules of the Matrix. You CAN do whatever you want. But if you ask the system what you can do, it will tell you a very limited featureset.
