No you're not. Argumentative and getting bitchy for random strawman arguments.

My apologies for taking yours, most hypothetical discussions I have still operate under the pretense of reality and what's currently possible.

I imagine if they were 100% effective by some means, you still wouldn't be very popular. Lies are a pretty common part of human conversation. You might get sick of them constantly alarming you for small, white lies. Unless you could filter them to only alert for bigger lies, in which case they'd probably find some use by law enforcement and intelligence agencies, but probably still not be very well-liked by the average person.
