Are you old when you can recall technology from the past? Technology that either no longer exists, or the name you use for it is no longer in use.
My father used to say photostat and fax. In my youth there was dial-up and BBS. The device halfway between a smartphone and tablet was a phablet. We had MP3 players like the Creative Rhomba, flip phones that fit in the palm of your hands. PDAs. All forgotten like tears in the rain. Saved in our memories, while they last.
Saving. That reminds me, most children today do not know where the save icon comes from. The good old floppy disk. Not the 5.25 inch, the real floppy, but the 3.5 inch rigid 720MB SD (880 Amiga) or 1.44HD.
Old technology. Guru meditations.
