"The old joke is true about calling the grandchildren when having computer or cell phone problems as one of the three year old's in my family is very good at navigating the computer or smart phones."
Some of my friends & I had some sort of computers & digital watches since 1980. We're all grandpa age now. My first chance to regularly poke with a computer was in school in the late 1960s though.
It would be hard to find any kid that can teach us anything about computers.
My mom in 1980 was better on a computer than I was. She had some unbelievable typing skills. So actually wrote a lot of computer programs for us. She was a grandma by then. But my sister or I had to set her digital watch for her. She was the first one in the family to have her own website (An astrology page). The following year she was a "Great Granndma".
I thought, I gotta get off the usenet, & make a website on the new internet after seeing she could do it.
It depends what your brain was raised & trained to do. Knowing how to set your grandparents digital watch or wifi is pointless, if they can't even sew a button on a shirt, work a non-electric can opener, change a tire, or manually light their hot water tank.
There's way too many people these days where if their power went out for more than a few hours in the middle of winter, if their vehicle won't start or is snowed in, & it's too far to walk somewhere warm enough, they would probably die.
Then I see all the young people shivering like crazy after just a few minutes in the cold outside. How many more years is it gonna take them to figure out how to dress for cold weather? Great on an x-box, but don't know what to do when it get's cold outside every year.
I see them with a $600-$1,000 phone, & they think they're such a techno-whiz even though they break it once or twice a year. Look at this kids -- my $49 phone does the same thing, won't break, the battery lasts longer, & when the battery gets very old, I can replace it myself for about $5. I don't need to download or install an app to get it to do something either. It does everything the app does, without an app most of the time.
They're buying computers & phones where 2/3 to 90% of their processing power is being sucked up just by the OS, telemetry/spyware, & adware in it. But they think they're a whiz because they have a bright shiny new computer that they know how to play games & chat on.
They know all the stupid hack tricks for their x-box, but don't have a clue how to unclog their sink or toilet, or how to prevent clogging it in the first place.
Many of the them can't cook a meal beyond a bowl of cereal, microwaving something from the fridge or a can, & making a sandwich.
And I don't consider spending 1-3 hours every weekday, & most of the weekend evenings or nights playing the violent video war game, Fortnite a "skill" or usefull in any way.
