With regards to AI progress is not guaranteed. Unlike say Moore's Law, it is not given that AI will progress at a linear rate. People say, oh look how fast it has gotten "smarter" and assume that rate of growth as a constant. It is not. We have no idea when the next breakthrough in AI will be. Also, there are signs that progress has slowed and that training on larger and larger data set does not guarantee better results. So marketing hype aside, I don't think we need to fear AI, it's not taking any jobs any time soon. It's just another tool.
