The fact that websites and apps are constantly changing the ui just for the sake of change makes things ever harder to understand for boomers.
My uncle didnt even know how to use youtube when the web redesign happened.
There really is no design consistency im software anymore. I remember having a class on making Windows programs in visual basic, and there were sections on how to make the UI consistent and usable, and the common designs practices most people followed (ex: the placement of the OK, Cancel, and apply buttons on a dialog box, alt key shortcuts for common menu options,etc)
