The computer does respond. With the result of the query or the operation that I've tasked it to do. If I say `<command>`, the only replies that I expect are: confirmation if the action is dangerous; error messages if the action did not succeed; and success message if it did. I don't want to do philosophy with a tool. I only want to get a task done or create something. All the meanings for the commands are already listed in the manuals for the software that are running on the computer. And you can get training if you want targeted guidance.
