"We buy cars and go to mechanics, right? We don't know how to peek inside the engines anymore." I don't know which world you live in, but it sure isn't mine! Even at the height of working as a senior system engineer / technical architect in the heart of Silicon Valley, I regularly wrenched on my car; I even found a self-wrench shop near the Tesla factory in Fremont. In fact I just wrenched on my car this past weekend. I wrench on all my cars. How could I call myself an engineer without understanding what I use?
