I think I’ve had both really great clients (thankfully) and worked with really bad designers (award-winning know-it-all type who only contribute by talking a lot).
So the exaggeration here is mostly to survive in the clickbait era, but the trend is happening. And to sum it up in a much shorter way — if someone is TRULY dedicated to their startup and truly believe in it, they tend to be able to come up with pretty good ux-grunt-work.
And yes, after that we take over and guide them further — modifying, simplifying and at the end making it pretty and developer ready.
And frankly I really like that shift. But that’s just me and my way of working — I hate meetings, I hate design by committee and I even hate when people open my Sketch files and make changes themselves ;-)
I actually stopped calling myself a UX designer, I just design products that work well and look good ;-)
