I agree with all your words. The job thing surely is a topic, but what I think really is the biggest "danger" is that Humanity is making itself too heavily reliant on technologies without having in store any plan B. Imagine how much stress it causes for people already when their mobile phone with all their data on it malfunctions.
There is just ever more information people need to consider and take care of in whatever it is, overtaxing the brain's capacity, hence requiring the execution of more and more "commands" to keep everything in place, like a machine which repeats motion sequences over and over according to a certain code. This again leads to overdrive of certain parts of the brain yet inactivity of others, making them rudimentary like a whale's feet. These inactive parts are mostly the ones responsible for our creativity, the absence of which in turn aggravates the conception of ideas for a plan B if this should ever be necessary...

Books dwindle while AI is entrusted with storing all data. Interesting scenario if all data got lost somehow without any chance of data recovery..
