I think of myself as an old dog programmer, making software (for others) since 1992... Still I think premature optimization kills performance, not that of software, but that of the developers or teams. We produce value in the form or automating stuff or out-right enable user to solve their problems in the first place. Also I love accessible code, that's explicit and gives enough context. Even code comments sometimes make things easier. I call BS on devs declaring the code does all the talking itself while at the same time hide functionality behind layers of useless abstraction "just to be modular" (for the sake of being modular).

Senior developers that mean business will coach you with your ways and will keep things as approachable/axcessible as possible while aiming for a goal.

If the goal is writing and optimizing code for embedded systems with tight restrictions, then fine. If it's working on web apps where the code mostly waits for user interaction, also fine.

Just my two cents.

Kind regards,
