I think I agree with the author here. Code is a tool. This is like saying "a wrench can be the solution and a good wrench is even more valuable". I'm sure that car mechanics have very strong opinions about various wrenches. But I'm paying to get my car fixed. Sure, it's nice to hear that your shop has the latest equipment, but at the end of the day, the thing that matters most is that you can fix my car.
Even as a developer, I hardly care about the code quality or what language you use if you provide a good and reliable service. I've never thought to myself, geez, I love AWS, but I really wish they'd move away from Java.
