What is interesting to me is that we have gone from having computers go from giant obscure machines in room, leased by large corporations, to having them all over the place in your house. There is a gradation of expertise and capability as there are with cars or other complex systems. From 'tinkerer' (usually a hobbyist) to 'mechanic' (who earns money adjusting and fixing) to 'engineer' (who earns money designing from scratch). They also come with different financial liabilities.

And that last bit is something that computers have largely avoided by consistently disclaiming all warranties. When that changes, and programmers (or their employers) are held liable for the incidental or consequential damage caused by their bugs, you will see a much stricter code for hiring and employing people who write code that runs on other people computers.
