The author's casual arrogance about "pixel pushers" only caring about "hotdog stand colors" is just as damaging to the profession -- as it infects the hardest part of getting things right most of the time: teamwork.
I care far, far more about data-structures, eventual-consistency, data-design, and types than CSS and divs.
These days getting the design to look nice is my two-hour reward for nine days of data-stitching hell, writing backend-for-frontend lambda functions, and negotiating API contracts that actually support the product I've been asked to build.
We need to stop assuming that just because a programmer works on client code, that they are in any way less capable that a programmer that works on server code. My point stands: It's absolutely toxic to collaboration, which is the key to success.
