These devices are already dying. Alexa, Cortana, Google Assistant, Bixby, whatever Apple's whore is called. All these programs are dying or dead ends. Google and Apple's self-driving divisions are gone. Tesla's is a driving assist mode only because that is all it will ever be. This technology is too unreliable, even with more advanced everything. Self-targeting weapons is the perfect example of this, it's useless on its own. It can only enhance/support human guidance. This shit can only be used off-world and even then, in most basic functions where life is not present. The technology as used in science fiction will never exist. It can't, the limitations are too great.
