I believe Dick also later said another aspect of the "reflex machines" that he was describing is that they only cared about their own self pleasure and desires - something that I'd say is a strong aspect of Bob and other consoomers like him. They exist to "consume product and get excited for next product," demanding that their own shallow whims be constantly fulfilled - give me the next sugary cereal! Give me the next Marvel Movie! Give me the next Funko Pop!
Your mentioning of people being turned into automotans via social conditioning brings me back to
@GuntPunt's theory that corporations and social media site like Reddit are actively trying to condition people into being MovieBob types for the sake of selling product. That's a frightening idea - that corporations are actively trying to turn humans into androids.
