Earlier quoted context omitted.
If a manufacturer is confident that their product will last, they can convey this to the buyer by providing a really good warranty.
A really long warranty only helps if the company remains solvent. I would be happier with something the manufacturer was confident was serviceable. Control boards that approach the cost of a high end smartphone are unreasonable, but also common.
I wonder, truly, if this would be successful. I have no way of even wrapping my head around how to get something like that off the ground.
I think if someone designed and shipped a car, for instance, that was completely serviceable by the owner and designed with that in mind first and for most, you could easily disrupt the car market for a very broad amount of people today.
