What a ridiculously untrue and narrow-minded statement. If you've only worked at companies where you're one tiny cog amidst ten thousand employees, sure, you may have a designer or psychologist who specializes in UI/UX analysis. However, that does not describe the VAST MAJORITY of tech teams, and frankly, any frontend developer who isn't analyzing their output or at least taking a moment to think "hey, maybe 39 scrolls is too much for this task," doesn't really care about or understand what they're doing.
