Really good software has automation built in, in the form of macros/scripting.

One of the reasons my bash terminal is more effective than point and click is the easy of automation of routine tasks: from history and aliases to scripting.

Software interop is trickier as it doesn't so much depend on being able to send messages from one piece of software to another, it's you need an agreed format of those messages ( whether they be expressed in the payload of an API, or a UI specific stream of point and clicks ).
