We have to adapt to the new environment in order to survive, try to prepare and watch for the warning signs.
The entire discussion on whether AI is good or bad for someone, let alone if it's coming or not, is missing the point. The main question is not whether it's coming, not even when it's coming, but how we prepare for it and deal with it in a good way. It's a bit like climate change.
Looking at it like a threat, using words like "survive" and "warning signs", is necessary only if you assume we're each to our own, playing a zero-sum-game. Once you zoom out to a society-view you might realise that AI (like previous technological revolutions) holds a huge potential to improve the human condition. Of course it also has the potential to hurt a lot of people on the way (like e.g. the industrial revolution), but this is
not inevitable, and is more a matter of social perspective - do you let "the system" alone, to work out a new equilibrium, let people compete against each other with the fittest / luckiest "surviving" at the expense of the rest, or do you plan ahead so that everyone wins to an extent?
AI or not, we've already reached the point where technically not all humans are required to work for
everyone to live very comfortably. This is going to get even more extreme in the future. The reasons it's hard to see (and easy to forget), let alone impossible to implement, are in the prevailing social, political and economical systems. Basically, humanity (or individual countries) has a choice between embracing that reality and reorganizing so that everyone is reasonably well off, or keeping the current paradigm that will inevitably lead to a well-being chasm between a tiny minority that has everything and masses (billions) that have nothing and are barely surviving. It may be enticing for some of us to believe we'll end up on top, but there's a much larger probability we won't. As the trend continues, slipping over the edge will become very abrupt and there will hardly be any chance for the individual of ever coming back.
