I don’t have a rational reason for this, but I think anthropomorphizing machines makes more sense on an emotional level for dumb machines than for smart ones. Kind of like the brave little toaster, or Wall-E going against the space ship’s autopilot. I guess part of it might be that we see the limitations dumb machines have and it reminds us about our own flaws and limitations, which makes us empathize with a Roomba more than with Alexa or ChatGPT.
