Cameras and camcorders are now old technology. Although there will be people who still like developing negatives. This will become a niche hobby like vinyl records, stamps, postcards and coin collecting.
With the current trend for pre-loved/vintage clothes I think many more folks are getting into sewing.
Every other TV programme is food related, my GC have all started baking:cooking as soon as they could stand at the kitchen table. Not sure if cooking will ever disappear.
We are a nation of foodies. I can’t imagine napkins and tablecloths, home cooking or restaurants and pubs disappearing - there are plenty of younger people enjoying them all, and many of them like formal tables.
Manners won’t disappear with us. My son and his friends were brought up to have good manners and they aren’t alone, though sadly a great many younger people seem totally unaware of what manners are. Also some not so young people - I was very surprised to see Jay Blades keeping his cap on in a Church.
Plug-in satnavs (I actually use mine although I don’t go very far now). Both DDs use their ‘phones and of course newer cars are fitted with inbuilt ones.
Potato peelers - for jacket and new potatoes I leave the skin on. for chips and mash I use frozen potatoes. Making pastry - I haven't made pastry in years - frozen pastry is better than any I ever made! Photo albums - Sadly!
