At some point the human race will figure out how to augment it’s brains using technology and will pass from the scene and be replaced by super-intelligent robots. Some have argued that these robots will not be religious. I believe some of them will be. It is possible that the robots will reflect upon the mystery of life with reverence, and if not, some robots may wish to have the robots be religious, worshiping a deity or deity, and will build them to be religious. By either path there will be religious robots.
Some believe that these super-intelligent robots of the future will not cook the books — i.e. they will not have one set of books for the tax man that misstates their profits and losses, and another real set of books. I don’t see why this should be the case. Presumably the robots will have some common interests — analogous to our state — and also private interests — analogous to our personal bank accounts. The robots that wish to keep more of limited resources for themselves would either control the information about their resources (whatever the robot analogy of money is) as it travels to the agency that keeps track of the robot communal projects, or will build robots to do so.
Some believe super-intelligent robots of the future will not have sex and fall in love and be jealous. I don’t see why not. There will be some decisions about how robots reproduce themselves. These decisions if they require more than one robot to participate will be the robot analogue of our sex. There will be robots who become emotionally obsessed with joining with other robots to reproduce themselves with them and this will be the robotic analogy of romantic love. And sometimes these agreements will be broken and this will cause robot jealousy.
Some believe all robots will moosh together into a single hive organsm called the singularity. I don’t see why anybody should expect this. When australopithecus evolve into homo sapiens we did not merge into a singularity. We split into nations, religions, families, and back-stabbing swindling individuals. Why wouldn’t super-intelligent robots be equally riven by conflict and competition?
Unless you have a clear reason for why some human trait will vanish when we are replaced by robots, the best way to imagine robots is to imagine them as humans but super.
I am sure there will also be atheist robots, and robots that pay their taxes and conduct their sexual lives in a rational fashion. These might be secular protestant robots.
