I think younger generations are getting more and more used to a digital-only workflow. I see also a shift in working habits from nine-to-five-office-work to asynchronical world-distributed work, which demands a such a workflow.
One of the things I really like about scrum is that it forces people to interact together. That builds team trust and solidarity. Those can be built in other ways, but it is much harder. If you want a great team, you need to build it somehow.
