Found this in the comments section of an article in The Register (Software CEO tells Catholic uni panel AI won't take out jobs, but it could take out brains):

School kids are now using the phrase 'that's so AI' to describe things they don't believe and are untrue.... there's hope for the next generation after all.

This is an innovation which I approve of. Hopefully it'll displace the yoof's casual abuse of the word "gay" to mean "stupid", which would make it a double win.
