Unfortunately, there's whole industries built around fooling people. It seems to me that we select for people who are good at fooling people and they become wealthy and successful. What would be nice is if we could start selecting for knowledgeable, helpful and useful people instead where insane amounts of money might actually bring some benefit to humanity rather than being spent on plunging us into dystopia.
That doesn't make it useful, unless you think fooling people is itself a goal.
