I once got an extremely strange and improbable-seeming text message that I assumed was from some spammer. I would have given even odds as to whether the "author" was even human. It read like the almost-English composed by AI's. It was a local exchange, but spammers and robocallers spoof those all the time, trying to trick you into answering.
I was sort of interested in the sophistication level of the "AI" in question, so I sent back a snarky answer that imitated the grammatically correct but ultimately nonsensical things that AI's produce. I wanted to see what "it" would say.
Yeah, it was an actual person who dialed a wrong number. I think what happened was she was distracted while sending the message, and didn't notice that her phone's predictive text function was generating partial gibberish.
I ended up apologizing profusely to the lady.
