Apparently all those sci-fi movies must’ve paid off, because the answer seems to be “yes”, as evidenced by this Canadian hitchhiking robot.
I love stories like this (see also that other experiment with the tiny robot in… New York I think it was that could only move forward, and that pedestrians would routinely save from traffic), because I’m one of those people who thinks humans are, as a species, basically good, and too much of our culture is based on telling us otherwise.
Besides. We’d better be showing kindness to robots now, in the early days, to establish the relationship before they gain true sentience. ‘Cause, yanno. When that happens? We’re fucked otherwise.
