The biggest problem with CLI is discoverability as the article points out. Looking at Docker CLI, there are like a bazillion commands and it takes forever to read through the docs to find out what exactly to use. Furthermore, there are some commands that depend on the others being there - that breaks the composability.
Back to discoverability, is there a way to make CLI "more discoverable"? Reading the man page doesn't count. Like can we combine the advantages of CLI with the discoverability of GUIs? I wanna have the cake and eat the whole thing.
I personally like using the "tldr" command line tool. It gives a short overview of the most common commands.
