Artificial intelligence (A.I.) makes it possible for machines to learn from experience, adjust to new stimulus, and perform human-like tasks, but they have yet to replace all of humankind because robots cannot smoke cannabis. A group in Los Angeles is behind a new multi-layered mixed reality project called Robot Prayers, which tests the boundaries of what robots and people can do together. For people and robots to smoke together, the A.I. would have to desire an altered state of programming operation, and require a simulated virtual THC especially designed for A.I. Many scientists think it would be illogical for A.I. to willingly partake in such a "mind" altering activity, but once computers become more self aware, they will have a mind of their own.
