Homogenous design is a good thing. The internet isn't nearly homogeneous enough actually. The mid-90s desktop apps got it right and we've been regressing ever since then because web designers are like kids with crayons.
UI Design is an art. Like any other art, it's bound to have constant currents and counter currents. More than the designer's whims, it's the population's need for novelty, generational differences, and the desire of companies to stand out what is driving the wheel.
The early web was filled with wacky and unique websites and it's a ubiquitously loved period of the internet.
This take is the death of joy.
Look up in an old city, look at the facades of the buildings. They have quirks, uniqueness, it makes the city almost a living thing. Every time we shave off another edge we lose that. Nevermind the fact that shoehorning everything into the same patterns is actually an antipattern and very good paradigms have been invented after the 90s.
It's not perfect, but I'd rather have a bit of a mess than boring emptiness.
