Why did UI's turn from practical to form over function?
E.g. Office 2003 vs Microsoft 365
It's easy to remember where everything is with a toolbar and menu bar, which allows access to any option in one click and hold move.
Seriously? Big ribbon and massive padding wasting space, as well as the ribbon being clunky to use.
Why did this happen?
The Ribbon is much better, and has been a part of the Office suite for over a decade, easily.
Poor examples aside, designers and engineers are rarely given a seat at the table in big tech companies. Most tech CEO's were either tech managers or sales people at some point, and are so far removed from IC work or valuing specific crafts for their user value that someone on the UX side probably doesn't get a say in how this shit is built.
Some UX designers either work to very specific business constraints, or work on stuff that has zero benefit to the end-user. Some engineers work on stuff that solely provides metrics for shareholders and leadership.
I'm tempted to set up a blog just to post about this subject, because it's everywhere, but big tech is now so top-heavy that for years many huge decisions have been made on a whim by execs. Tech has grown so large and powerful that tech execs (and those clinging to their coat-tails) put themselves outside of the echelons of what an IC can reach, and far above the user. Years of MBA double-speak and worshipping the altar of guys like Gates, Bezos, and Jobs means that it's "good" to be opinionated and ignore fact over your own judgement. This results in senior management deciding "let's put AI here" or "the colour scheme should be mostly white", despite reluctantly paying hundreds of people many thousands of dollars a year to KNOW about this stuff.
That, in essence, is why everything feels shitter nowadays. It's because some fifty-something MBA cunt believes that you need AI, or a good UI needs more buttons - stuff we've known for decades is fucking stupid. That's irrelevant though, because by being "General Manager of UI at MegaCorp" and having an assistant to arrange their Outlook calendar, they know more than you, pleb.
