Yes, but we went from a time where these optimizations were absolutely unavoidable (so unavoidable that programmers would sacrifice any other thing for it) to one where the optimizations may be a nice to have, but for most organizations the maintainability of the code is much more crucial.

As mentioned before there are exceptions, like embedded programming, anything that needs to be finished within predictable time (game code, graphics, DSP code, etc). But even if you write a thing for a company website today I wouldn't dare to answer if making the code 10% less readable to make it use memory 10% less memory is a good trade off. Not that redability and memory use are necessarily mutually exclusive goals, but if you highly optimize code for one dimension, others will suffer at some point. And if you come from a generation where memory usage was king, it could be that you make these trade offs out of habit or principle despite them maybe no longer aligning with the goals of the project you're working on.

Anybosy who is good at their craft will choose how to deal with trade offs depending on the needs of the project and not based on remembered tradition.

With 20 years of experience in website development, I have led various site speed optimization teams. From my background, I pay particular attention to assets, JS profiling, and related aspects whenever I work on a web app. These practices are so ingrained that I perform them automatically and transparently, as they have been part of my process ever since.

The same thing might happen to these engineers when working on existing or new projects and writing C/C++ code; these optimizations will be part of their process.
