> The days when a car aficionado could repair his or her own car are long past, due primarily to the high software content.

More likely, it's because all said software is proprietary. If people got the source code to their cars' computers, you'd see a lot more people repairing their cars (and a lot more interest in automobiles in the current generation, leading to real, open innovation in the space).

It's interesting to consider how cars went from being something anybody could hack on, to something that only a few "qualified" people are now able to service. I don't expect the same thing will happen with software (in other words, I don't think "trusted computing" will ever become the norm), but we must be sure that it never does if we want innovation to continue in the software space.
