"I'm a young master engineer"

I'm an old engineer (electronics and software), and as I age and gain experience I realize I still have a lot to learn. I don't think you can be a "young engineer" and a "master engineer" at the same time - and I think those who truly master engineering have become MORE adept at questioning their abilities.

I think the attitude conveyed by his tag-line is repeated (several times) in the article's body ... one mind-set, one "best" and everyone else must be wrong. His ideal seems to be centered around Madrid's transportation systems, but if your (singular) goal is what's good for the environment, I've seen many Asian cities that easily beat buses and trains (with walking and bicycling).

If you're living an unhurried continental life, walking to the local market and carrying home your fresh-picked vegetables might be an alternatively to taking the bus/train to a larger grocery store. If you're a hurried SF-based founder, a door-to-door service is optimizing for a limited amount of time. Why does there have to be just one "best"?

Here's an example ... suppose Elon Musk flies around the country in a corporate jet while working to promote solar energy at prices that will ultimately lead to a significant decrease in emissions. Should he instead bike across the country so his jet isn't polluting the skies? Or would the duration of each trip simply make it impossible to accomplish his goals?
