I get that question a lot. The answer depends on who's asking.
If it's the PhDs critiquing my work, I tell them I'm the world's first cognitive cyborg. Treefactor's next demo will involve playing AI Dungeon, and feature exciting production values such as audio commentary.
If it's my tyke, the answer is, "NO I AM NOT A ROBOT, ARE YOU A ROBOT?" to ruthless tickling.
It's pretty silly how tykes have infinite free time and appetite for repetition. Which is how I can say "I get that a lot," even if only one person asks...
