What we need is also open source, open documentation and open firmware. That way when manufacturers loose economic interest in software updates users can take over. Ie open source access should be enforced by law.

We also need modular hardware so that processors / main board the brain of the device can be replaced independently of the other hardware.

For example the entertainment system software of a car will get much more out of date than the physical hardware of the car itself. For environmental reasons this needs to be addressed. Same with other devices such as TVs the physical screen will last longer than the software in the device.
