What is happening is that there are now different sets of skills: touchscreen skills and keyboard skills. It isn't even that they are particularly good at using phones (students say they don't see email announcements because they don't check email. I ask them why they don't set up their phone with the university email. They say they don't know how) but that they use phones more and have less experience with laptops and desktop computers (while setting up for presentations I see them struggle to log into email or google slides. They type google and enter to go to google.com, then search for youtube, then at youtube they search for the video they want to show. Strangely, when they cut and past a url they almost always right click and select paste then hit return and nearly never use "paste and go" which is right below that in the context menu. They don't know ctrl+f.)
So if "digital natives" means anything, it doesn't mean that they are automatically good at tech.
