Very interesting topic! People are a threat to themselves. When people have control over objects that can harm them then they better be careful and focus on what they are up to. This applies as much to AI as to a gun, knife, or a lathe. I regard AI currently as more of an advanced pattern recognition system and since I have witnessed first hand how the average software developer struggles to even get CSS to jump through the correct hoops I am not too worried about some self-conscious AI going berserk. Of course, if those same programmers are going to be fiddling with code that launches tactical nukes then I would be a bit more worried. I will also be driving my own car for now, thanks Elon. As you have alluded to there are more fundamental issues that we need to solve before even getting to anything that is going to approximate awareness or, heaven forbid, self-awareness. We know we have matter and we know we have consciousness. If consciousness is as a result of some configuration of matter then it is something we can cook up in a lab. However, if matter was somehow "created" by consciousness or is somehow "experienced" as "real" then it is a whole other affair. A simple concept such as "size" would seem to me to be problematic. If some mean-spirited self-aware AI were to create robots to annihilate us then exactly how "big" would these be? It would need to understand something that we all take pretty much for granted. It is a similar conundrum with the evolution of wings: how on earth would wings sprout out of no knowledge of how "thick" the air is and how "big" the wings need to be in order to lift the bird? If it is a matter of chance then what records this monumental event in the DNA that produced "wings" that could have the bird fly and then also keep those same wings around in the same configuration? Would another pair of wings not be even better? I mean, we have this in software development: "Oh, a 5 page document resulted in a successful system... then 100 pages would be even better!" For now I'm quite happy to have AI spot faces and listen to requests for stuff. Especially the voice recognition is handy for kids that can't yet write/type what they are after but they know that they would like to see a "fan collection".
