There are so many reasons to dunk on Elon, but this isn't one of them. Generic looking humanoid robots isn't "ripping off" I, Robot. It's literally the most common depiction of futuristic robots around.
You wanna dunk on Musk? Talk about how his robots were remote controlled with humans talking through them. Talk about how most of his family has disowned him and refuses to have anything to do with him. Talk about how he has Trump's dick firmly in his mouth because he might be in hot water over supplying equipment to Russia and might face prosecution if Trump isn't elected.
But this just screams of low-hanging Musk-bait, where journalists will write anything negative about him knowing that those who have hate-boners for the guy will eat up whatever crap they shit out, even if it doesn't make sense. It's like going "Elon Musk ate cereal for breakfast! What a fucking loser!"
