quarantine 'em

Ha ha! This so-called "A.I." machine learning algorithm made a dumb mistake! No fear of them ever taking over the world, right? [the algorithm is put in charge of the world] Ha ha! Hmm

Or to put it less obliquely, it's completely academic how effective or ineffective an A.I. is, what matters is how much power we surrender to it

It's super easy to hide behind an algorithm. "Machine says no, so, no. I cannot acknowledge your unique circumstances. Go away. Call the automated line again"

Note that in the above scenario the system has already "failed" because someone's reached a human. "Ideal" universe, there is only the automated line which always says "no"

Note that the fact that a machine which always says "no" is not really an "A.I." doesn't affect your ability to hide behind it
