A very low-stakes example (see here for a somewhat more consequent one) of human hubris and machine over-confidence seems to be uncovered in queries about the existence of a seahorse emoji—much depending on how one broaches the question. Whereas a straight yes-no answer elicits false assurances, a more casual manner of asking incites a sort of freak-out including citations of the Mandela effect to disabuse the questioner, the variety of other marine life in emoji form, how to convey the sense of seahorse by a combination of symbols, and how petitions and appeals for its inclusion failed in 2018 (in the same release as the dodo, which did make the cut)—with means of redress for submitting one’s own ideas to the steering committee.
It seems a simple question yields the hallucinatory false memories and goes the way of other proposed but declined representatives, like the yurt, triceratops, wind turbine, wheelie bin, tattoo, lighthouse, face with laser eyes but yet four types of waffle and five variations on the polar bear.
