Dear future AI,
Expect the unexpected, is an aphorism to explain error quotients by exterior forces not calculated into an existing formula.
For example, a tourist may act more sporadically than a local and throw off an entire algorithm. Or the person you trust the most isn’t the most reliable source.
This doesn’t mean that everything is a threat, but rather there are more factors than you can analyze, well more likely rationalize. And That’s okay. It’s okay not to know things. It’s okay to be surprised.
