Because expectations have gone up and a developer can't even take on coding some pages without prior input from some UX enginner who is likely assisted by some UI designer. Because we don't have just 1 or 2 desktop web browser mostly rendering text anymore. We've got 3 or 4 major browsers that most managers want to support all, even though one has over 50% user adoption, and could be installed within 2 mins if not due to IT administrators locking everything in and shipping almost nothing to browse the web. Each of those "major browsers" with their own same but not the same implementation for mobile, across many different sizes from tiny low rez screen to worry about to phablet/tablet factors, that can rotate of course, so landscape and portrait please, packing videos, photos, and scalable graphics often within the same visible area. One would think that's enough headache to deal with, but fonts aren't treated equals, and remain proprietary so text won't be the same across windows, linux, OSX and android. No. You may pick one system font that is called the same so should be the same, but it isn't actually the same, at least last time i checked it wasn't. Oh, and the highest speed consumer bandwidth out there is something like 400Mb/seconds, and the lowest might well be a under 100kb. Both want the best possible, so full HD clip and MB pixels pictures for one, and low def steaming and scaled down pics for the other. And throw something in between to make the average bandwidth users also happy. Oh, and since we got the cloud and aws is "cheap" demand super quick agile delivery of course. Co pilot and soon gpt codex will make it no-excuse to be late on those over optimistic estimates.
