Human wake word recognition isn't infallible, either. How often in your life did you respond because you thought somebody called your name and it wasn't actually the case?

I wrote that in to deter kinda-bad-faith responses, where someone tries to play at being an evil-genie, inserting unreasonable flaws into the gaps, like: "But what if it triggered all the time? On purpose!?"

The point is that ethical implementations do exist, and them working does not rely on anything close to perfection--so nitpicking that word isn't helpful.
