Interesting Post! I am part of the older generation, and I don't necessarily think that there is more stress today than in earlier years. I totally agree with what you say about technology being a disrupter, but quite frankly technology has been a disrupter since we began harnessing electricity.
I think that the only people that are stressed by the rapid changes in technology are the people that resist it. Either get on board, or get passed by. We need to learn to embrace the change and explore the new opportunities that are created through the adoption.
I see that you are looking at it from a different view point and that is completely fine. My view was more towards the lack of peace that comes from the overuse and misuse of technology that we see in the case of millennials.
