  ... unless it's something like a forgotten index in a database. Which can easily make a difference for a factor 10 or more. That's the problem with computing: Often you don't have a very good understanding if there's a good reason for the thing to be slow. Only if there is such a conceptual reason (like, you're solving a problem involving very many variables that must be optimized), you must start thinking if a different approach is in order.

  Which is just what the guy describes in his article. At least, thats how I read it. If you only hire people who only know about cars, you're fucked. You'd need someone who knows about a ton of different transport "technologies", and knows, say, that you can combine the technologies optimally, say taking a shuttle to the airport whereas the trolly station terminates two miles away and the cab rank is always empty.
