I wouldn't consider everything that is described as AI by various people, companies, marketing departments, etc. as being true AI. I'm skeptical that AI exists in the sense of a digital entity that is capable of cognition, mimics and/or surpasses animal/human brains, and will eventually begin seeking out knowledge on its own once it reaches a certain point of maturity/advancement. In other words a digital creature (for lack of better term) that could eventually reach a level of super-intelligence. But we do have some really cool AI stuff like IBM's Watson. I do not consider the home automation and assistant stuff like Amazon's Alexa, Google's Assistant, Apple's Siri, MS's Cortana to be anywhere near the advanced level of Watson though. IMO, Watson is a magnitude, if not several magnitudes, more advanced in AI than the home assistants like Alexa, Google, Siri, and Cortana. I think Alexa, Google, Siri, and Cortana are little more than huge data bases stored on server farms and accessed by some sophisticated software algorithms. They certainly are not very intelligent yet, at least in comparison with Watson. But to be honest, we are a long way from Mr. Scot asking the computer to solve a complex engineering issue with dilithium crystals!
What we can do is program the computers to tackle specific tasks in order to solve specific problems. But is that really AI or just good computer programming by human intelligence? I don't know the answer to that, but I suspect we are still much closer to HI in this technology than to true AI.
