I agree with most everyone above. Nothing in Alexa, Google or anyone else shows real AI. It's all trying and it purports to figure things out, but when you think about it, 99.9% is lightning fast table lookup.
The other .1% is lost. At this point in computers, computers can't think. I'm not scared of AI, I look forward to successful demonstrations and implementations of it.
The other day, in an attempt to give AI the benefit of the doubt I simply told Google to open the garage door. The a few minutes later with the door open, I told it to open it again. Google said OK. A few minutes after that, I closed the garage door by using the button supplied with the door opener and my system went bonkers. I got text messages saying the door was open when it was closed, etc. What a mess. Then I had to remind myself, it's ARTIFICIAL intelligence, not real intelligence, I shouldn't have expected more.
If I employed the above scenario without Google, my Homeseer events would handle things just fine. Meanwhile, there are thousands of scientists out there working on AI and I wish them all the best. Bring your best example to the forefront and make our lives that much better for it.
