> "to prove how clever you are"

I see this a lot and I just don't get it. Is a mechanic who uses air tools trying to "prove how clever he is"?

Knowing more than one tool allows you to choose the right tool for the job. Assuming arrogance and a motive of "proving cleverness" sounds like a great way to pick a fight.

this is not a valid comparison.

a mechanics' tools would be IDE, build tools etc- I'm not interested how every dev uses personal level tools.

But just writing a program with a new dev stack without thinking of the possible consequences is just plain unprofessional.

Air tools are fine -- after the car left mechanic's garage, I cannot tell if air, electric or manual tools are used.

But if I give my car to mechanic for carb cleaning and tune-up, and get it back with fuel injection system and explanation "it is better anyway", I would be very unhappy.

There are no parallels in the real world to how programmers chose and use languages, frameworks and tools.
