I could also go to a med school and remove my own appendix. I shouldn’t have to go to a trade school and buy computers and software to work on a car. Most of the updates on the vehicles are proprietary software, so maybe I should then go to a college and get a degree and write my own software. Then when I get hungry I’ll buy a farm raise some cattle, go to school to learn how to get all the right cuts of beef, slaughter the cow and have steaks for life.
