This is a description that turns on every red light in my head: "netflix for", "binge watching", "turning into", "keep you hooked", "but smarter" etc. - probably I'm not the target age demographic or maybe this is an American thing? Also, the meaning of literal, here, would be something like having a hamster named Duolingo and you built a gun to kill the animal. That's a literal killer appliance.
