There have been a few over time. It originally started out as a project to test some new Reddit features with fake users, using Markov/GPT-2 bots, and then it became funny enough to let users see.
Them calling themselves bots or coincidentally being unable to tell cats and dogs apart was also quite funny back in the day. (They didn’t do any actual image recognition, it was just making links and a title.)
More than a decade on, and it’s still one of the best kindles ever made, in my opinion.
You had physical buttons instead of a fiddly touch-screen, you could have music, have it read to you, and also go on the internet.
Plus it’s old enough it supports a bunch of formats, and registers as a mass storage device to a computer, so anything can use it.
