The integration also leads ro low prices though: A bug trinitron used to be $1500-$2000. Today you can get a 4k TV that is twice as big, much cheaper to run, and beats the 1080i that the largest tubes could support 20 years ago. The lower upfront coat just wins, especially when technology keeps improving so fast you'd rather get the new thing than repair the old one at, say, half the price
yeah, but we're talking about cars. Do we want to make cars disposable? Should people throw away their car every 12 years when parts are no longer made or the battery dies?
Apparently the average car is about 12 years old hone it's scrapped; so we basically are already there.
If by making everything more reliable but hard to repair, they'd reliably go 12 years before exploding, I think it'd be a net win, as long as we had adequate recycling options available.
The average age of a vehicle on the road in the U.S. is 12.6 years. The total number of vehicles registered in the past 20 years is only up about 20%, so the average age of a vehicle being scrapped is more like 23 years. That also doesn't account for the fact that many older vehicles that are deregistered aren't even scrapped, they're sent to Mexico or overseas for a second life.
The massively lower repairability of modern cars, especially from sensors and airbags is going to significantly lower this lifetime IMO.
I get how mass manufacturing works but it's crazy too seeing people walk on the side of a massive parking lot where cars are just sitting there not used (not sold yet).
Unless cars become extremely cheap (they have done the opposite), it will never be acceptable for them to be disposable. Materials and processes are better than ever yet cars are becoming less repairable. Manufacturers deliberately make things difficult to repair to encourage people to buy new cars, but that only goes as far as people will tolerate it. We aren't talking about pocket change. A new car is usually in the top two largest purchases anyone makes, and they really should be built to last at least 20 years. There's no reason why they can't be built to last 50 or 100 years, or indefinitely (with repairs).
