You are right that you are being efficient and reasonable, but also you are right that you sound like a dinosaur. This is the same for people who cling to C as "this is all I need", possibly producing beautiful efficient code with no VMs or slow interpreters, at the cost of lower cooperation with their colleagues.
The bottom line is your choice of tools is also a social thing. Rejecting the mainstream tooling can be appreciated by some, confuse others, and sadly developers with lower self confidence might even see it as a form of insult.

Well, that’s all I needed to hear. What’s the point of not sounding old-fashioned when the new fashion is worse? Considering the social point, why not be more critical when the efficient and reasonable thing is derided by others as old-fashioned? Why not expect those people to update their world view?
