It does have a meaning. It's a pop culture reference.

No, we haven’t decided that inception is synonymous with recursion, but even if we had, lots and lots of words have always had multiple meanings, and meanings that come and go, and meanings that change over time. Language is fluid and is defined by its usage and not by static prescription, which is one of the fun aspects of language. Embrace it and enjoy the ride! ;)

If language never evolved, then most of us would be "instructors of the sentient hunks of distilled sand."

Doesn't that sound so much cooler than software engineer or programmer though?
