Being able to operater a car doesn’t make one a mechanic.

Living in a house does not make one an architect.

and

Using electronic or other tech equipment doesn’t make one an engineer or “tech guru”.

No, but growing up in an environment where you're encouraged to look under the hood can help a lot. No offense to the "trained professionals", but I certainly try to do as much myself as possible. 1) Many times it turns out better and 2) I don't get cleaned out by having an endless parade of people doing/fixing things for me that I can do as well or better for much less money.
