It seems a lot of people almost entirely (willfully?) missed the point of this post.
Using the command line as the primary interface for an average computer user ended many years ago.
We're now seeing web browsers which implement functions to find and manipulate information through text based commands. A Command Line Interface.
The title is naturally hyperbolic, but the essential message is true. The command line 'died', but is now returning in the web browser address bar. It is the new command line.
