Car manufactures have engineers who work on removing enough metal from parts so that they will last just past the warranty and not much longer.
I find this deplorable.
The good side of this is that it will make the maker revolution that much easier. The bar for product quality is set really low. So, all of those home built jobbies are going to easily surpass what you get in the store. Plus, you can just make any replacement part. It will always be there; its just a digital file.
This is a very intersting comment and topic! Thanks!
