I love old sci-fi novel covers.
Look at this fella
He looks like the robot is sticking its fingers in the food while cooking family meal when the man knows the robot doesn’t wash his hands.
That’s probably why a lot of these books end up being disappointments. I’d open it up, and it would end up being the same old troperific writing we’ve grown accustomed to. I wish this was about a germaphobe teaching a robot to wash its hands. At the conclusion, the robot learns to wash its hands, but dies because the water short circuits the robot, and the doctor realizes the robot never used the restroom. But the question remains, why was the robot tasting the food.
