The thing that really bothers me is, as Alan Kay says: The ipad interface is designed for 2-year-olds and 82-year-olds and being forced upon everyone in between. See, eg: https://www.fastcompany.com/40435064/what-alan-kay-thinks-ab...
It is a de-evolution of problem-solving culture in the sense that people are discouraged from using more sophisticated tools to step up their game! "There's an app for that" culture implies that you don't need to learn to compose tools to solve problems -- sit back and consume somebody else's hard work. While that does simplify computers so that more people can use it in the short-term, it also strips away the whole purpose of computing, which is to empower people with a more advanced tool. That's what human cultural/civilizational evolution has been about -- from stone tools, to metals, to the industrial revolution, to the information/computing revolution. Forcing people to interact by tapping on graphical interfaces is to step backwards to caveman levels of communication: point and grunt. We're giving up on human language, writing and tool use, just so that people can avoid learning a little!
Not knowing to use a keyboard is not bad as such, if one's typing speed on a touchscreen can be as effective. But that's hard---at least for someone who hasn't grown up with touchscreens all over the place---and I had to switch from my phone to my laptop to type this long-ish comment! And the amount of typing, editing, reorganizing and adding links that I had to do would have been extremely difficult to do on a phone interface. Giving in to that barrier can so easily stop one from creating/contributing, and going into a passive consumption mode!
