It's crazy to see what kids can do these days. Heck, it took until the mid '80s before most people understood how a remote control worked (and some still can't figure them out).

Kids now can do everything short of mowing the lawn with their phones.  But chances are, they will never be able to say they know what these things are.

What did they leave out?  What things do you remember from your childhood that kids these days will never recognize?
