Rant: The old guy at the truck stop in Flagstaff who said 'real' mechanics don't use scan tools

I was fueling up my service truck last fall when this guy in his 70s, leaning against a beat-up Peterbilt, started talking shop. He saw my laptop on the passenger seat and asked if I was a 'computer mechanic.' I laughed it off, but he got serious. He said, 'A real mechanic can diagnose a bad injector by the sound of the exhaust and the smell of the fuel, not by reading a screen.' He told me a story about fixing a Cat 3406 in the desert in '89 with just a wrench and a piece of wire. I get respecting the old ways, but that's a dumb hill to die on. Modern engines have a hundred sensors; you can't just listen to them. You need the data. It stuck with me because it felt like he was calling my whole skillset fake. How many of you still run into this 'old school vs. new school' attitude on the road?

That reminds me of my uncle's shop, and brown.reese is right about using all the tools.

Good mechanics use every tool they can.

My old boss had this saying, "A tool is just a thought you can hold." He'd pull out a bent coat hanger or a piece of chalk before he ever grabbed the expensive scanner. It's about solving the problem, not just owning the gear.
