I don't really fear "rogue, malicious, biased, or otherwise harmful AI" as that is projecting human emotions and tendencies onto something that is not human. I fear that it is not truly artificial intelligence just as televisions in every living room did not truly offer privacy as Edward Snowden brought to light, that it is programmed responses and actions which would mean that someONE is pulling the strings. That is my only fear in regards to the whole things, to be honest. I don't see any reason for an AI to "destroy humans" as we are mutally beneficial to one another. I'm extrememly hopeful for the future, and I believe that we have to at least, if it is truly AI, give it a chance to rise or fall.
I think that the reason no one was talking about it was just because no one had the information. Everyone being informed and having an opionin didn't really become possible until almost every person had a screen in their hand givin them 24/7 access. We live in a very different world, and yet we always measure things against a past without those technological advances. In fact, on that note that's a positive attribute I would equivalate to AI. We lose generational knowledge and are forced to repeat these 80-100 year cycles in society, but with an AI that lives through these and can carry on our legacy from generation to generation with a first hand view point... That will change everything. I can't tell you how many nights I've spent stairing at the ceiling wondering if the history I was taught was what actually happened, or trying to understand the thoughts and mindset of anyone on the Earth at the time. Although it doesn't solve the issue of the past, it allows us to perserve the future.
Another huge innovation of the future (possibly the greatest), imagine the space exploration opportunities available when we can send a humanoid thinking entity that can simutaneously communicate with us from wherever it is because it's connected to every extension of itself!! We are moving towards a Star Trek style future, and that excites me. Weren't they even one of the first to predict cell phones? I feel like I remember hearing something about that. How much faster could AI robots build Elon Musk's terraformed Mars without dealing with the lack of oxygen in the process? What about the moon base? What about Titan?? Other universes??? We can't travel at the speed of light due to our molecular structure, but an AI can. What if you can operate the AI through a VR headset? So many possibilities.
