Caring about efficiency and performance doesn't have to mean spending all your time on it until you've exhausted every possible avenue. Sometimes using the right tools and development stack is enough to make massive gains.

Sometimes it means spending a couple extra minutes here or there to teach a junior about freeing memory on their PR.

No one is suggesting it has to be a zero-sum game, but it would be nice to bring some care for the engineering of the craft back into a field that is increasingly dominated by business case demands over all.
