To be blunt, we'd probably find the robots a lot more endearing if they placed themselves on an appropriate side of the Uncanny Valley.

Years ago, there was an IRC channel with a couple of simple Markov-chain bots and they were legitimately charming with their randomness, which ranged from "demented Pokemon repeating their name over and over" to "flash of insight". But you'd hardly be quoting them in a serious conversation to a co-worker or boss, and nobody was promising superintelligence any day now from then to justify tripling my electric bill.
