> You'll get a competent UI with little effort but nothing truly unique or mind-blowing.

The shelf-life of unique and mindblowing has reduced to a week (being generous) before it's copied by slop artists looking for a resume booster or funding, and months tops before it's part of training data for everyone. Unless you find it in that small time window everything will seem homogenous.

It could just be a systemic result; unless you deliberately take the lonely road to parts of the internet where other people aren't, you will not see unique and mind blowing things. Which by definition you can't source from a place that has a lot of users, like social media or popular forums.
