The comp for an older generation is cars. Cars saw similar growth and adoption in the 50s-80s. And they had similar growing pains, reliability and maintenance issues were common place. So being able to perform maintenance and having an understanding of how they work was far more wide spread than just hobbyist and professionals.
As cars advanced the need to perform field maintenance and ad hoc repairs became less required so future generations (on average) became less knowledgeable and skilled at various car repair (and modification) activities, because cars just work now so there’s really no need to worry about learning how to fix minor issues, because they’re just not a common problem.
Case in point: I drive an EV and I don’t think there’s a damn thing I personally can do to fix it other than maybe change a tire. It doesn’t even have a spare and I wouldn’t even know how anyway.
My god, I’m the iPad kid of cars.
There’s a lot you can still do. All the suspension, battery cooler pump, brakes, wheel bearings, a ton of things to do with the electrical system and lights, fuses and relays, window and lock motors, blinker arms and switches, fluid changes, hvac and ac components, the traction motors themselves…generally the only thing hard for a shade tree mechanic is the battery itself. They’re really heavy and hard to remove.
Now some components are going to be hard to get a hold of because there isn’t any third party companies making replacements, but eventually as need arises, they’ll get made. Until then there’s places like pick n pull where you can go take used parts off used vehicles or buy used and tested components from ebay if the manufacturer won’t sell you something. I bought a new oem hybrid battery just a couple years ago from a Toyota dealership and installed it myself.
You also can’t wrench on a car anymore in the way you used to. It’s all computerized and you need special software to access and configure parts.
I can’t replace my airbags without special pairing software that cost tens of thousands of dollars. It’s unlikely that I’ll learn by performing the repair because the tools are no longer available.
Eh…that’s still pretty doable. Many things actually got easier for auto work. A $12 bluetooth obdII dongle and a $4 piece of software on your phone will give you most all the trouble codes you need to diagnose problems, and that’s it it doesn’t outright tell you the issue. Almost no car parts are parts paired and thanks to the internet there’s guides that are way better than a Haines manual to show you how to fix things, as well as a dozen different places to order parts from.
In the past 15 years the only time I’ve used a mechanic was to replace a clutch.
Here I am at 41 and know how to screw with everything. I stayed inquisitive and stayed a tight ass. I think I’ve paid for a professional to do something twice in the past 20 years. I didn’t want to take on the task of replacing a clutch on a front wheel drive suv on the ground in my driveway.
The difference is that you don’t need to be car savvy not to get into an accident. But you do need to be tech savvy not to be at risk of cyberthreats.
Drivers truly don’t need to know how a car works, software is not like that.
Also, you can get by without a car, whereas most people need at least an email address.
Edit: I don’t understand the downvotes. Do people think that you need to know about how engines work to drive a car. Or do people don’t think you need to understand file structure to manage excel files?
