here's one. A set of car tires that don't wear out. Michelin is currently working on it.
I have news for you. They probably already have those. But they will never see the light of day in the marketplace. Just like they already have stoves, refrigerators, washing machines, and dishwashers that last 100 years. And they probably do a better job than the ones made today.
Go buy any of these things built in the late 1800's-1920's if you can find them, and you will probably find them still working just fine.
It's called planned obsolescence, and our bizarro world economy goes to shit without it.
My grandfather recently died at the age of 94. He had been married to my grandmother for over 70 years. All of which were spent pretty much in the same house in Centralia Illinois.
Both their parents were farmers. When they got married, both sets of parents chipped in and gave them a hand a me down stove/oven, refrigerator, washer, and tractor mower. Every single one of these items was at least 90 years old when I moved my grandmother out of her house in 2013. Some of them much older. And all were still working just fine.
As to the TS query, I am going to go with the
'features and age changeable- can not tell the difference between a real woman robotic fuck toy- with the bonus personality management chip of course'. Or 'Roboconcubine' if you will.
Imagine being able to take a quick picture of a hot chick walking down the street, or rip a pic of a hot celebrity out of a magazine. Then you plug it in to your Roboconcubine and you are off to the races. And it's technically not even cheating on your wife!!!
I hope they have figured out immortality by the day the Roboconcubine is invented. otherwise humanity is doomed.
