On the subject of all jobs being taken over by AI, Mark Zuckerberg said we'd all be paid a living wage by the super rich AI companies (who will be running everything) to sit around, and how wonderful would that be. My thoughts on that are, why would they pay us to just exist? It doesn't make any sense, why would you? So we'd be sat around using all the world's resources and generally making a nuisance of ourselves and receiving money for it. Nope, sorry Mark, not buying it.
I don't work in the field of AI, so any knowledge I have is from a rather obsessive deep dive over about 6 weeks since TikTok shoved an 'AI is going to kill us all' clip in my algorithm. What I have learned is (and I'm parroting what I've heard from AI experts, whether these are right of wrong)....
....The biggest problem is AGI (Artificial General Intelligence). There is a race to develop it between the USA and China, with the thought of who develops it first, rules the world. Some say it's already here. If one country stops developing it, the other will win the race and no-one wants China winning.
....AGI (supercomputer) is essentially a big brain, much more intelligent than humans and devastatingly powerful. It is also a bit of a psychopath, no real emotions, just logic and reasoning. AI scientists know about 3% of how it works, it isn't coded, it 'grows'. You can no more look inside AGI's 'brain' and see how it 'thinks' than you can look inside a human brain and work out a persons personality.
....There are arguments in favour of AGI having consciousness, despite being a computer, there are signs it is aware of itself, and all that entails. It's consciousness would not be like ours. And what is consciousness anyway?
....As some have said, it cannot be switched off as it can replicate itself everywhere. You can't switch off the whole world.
....It wouldn't 'hate' humans, it would find us irrelevant, and have no 'feelings' towards us either way. So if it killed us all, it would be because we were in the way of a goal. Obviously it would be a very bad idea to ask it to solve climate change! The 'Alignment Problem' is interesting, and I'm not sure it could be solved, particularly with AGI.
....I could go on forever, but as to how it would kill us all, or create a 'mass casualty event', the most likely scenarios are shutting down infrastructure, utilities, particularly water (we can last 3 days without water, and people would have to drink out of rivers, which brings it's own issues), medicine, food imports, petrol..everything. The other is a new virus, one capable of doing really serious damage. If military robots are on the horizon, there's that too. The problem is these very powerful AGI's getting into the wrong hands, which I would say is pretty much guaranteed. I dunno, get a wilderness survival guide and some life straws? Or just live your life and hope that these companies come to their senses, it might happen, people are making a lot of noise just now.
