My earlier post was in fact a little tongue in cheek (To a certain extent)
Times change, book learning, seemingly a thing of the past, with 'Google' at one's fingertips, giving 'Instant facts' for people to chew on.
Food for thought about how they managed in the Nelson days of sail, maybe months to get a message around the world, with all the faffing about at the time. Then radio with Morse code, all those dits & dars.
Then computer time, at first a thing for specialists, then gradually creeping into the wider world. School sprogs in America, with a computer terminal, waiting patiently for their own terminal to come online for an hour, to they could experiment with their own self taught program for 'Noughts & crosses (Tick tak toe) for the Americans.
Now, we have reached the stage where the utterly brainless are adept at using computers, thanks to the 'Plug & play' & all coding done for them.
So, the young never look in wonder at 'Colour television' any longer, times change.
In my opinion, the service person of today, is still made of the same stuff, just different times.
