I blame the confirmation bias of social media for the
current state of dissed-discourse we find ourselves in these
days.

But this suggestion misses my point entirely. And the point
is, we shouldn't have to pick-up the "box" (aka: file) and
shake it (ook-ook) just to "intuit" what is inside. Using
file extentions (aka: labels) solves this semantical problem
much more elegantly. Now, is a perfect solution? Of course
not! However, it is the most practical solution.

And although an automated "intuitor" could easily determine
if a file contained a markup language, we would still be
force to "shake the box" by running it.
