I'm surprised nobody has mentioned the International Building code. There is a reason everything is starting to look the same, safety, building code, access to this information and globalization all play a part.

If you perform a surgery a certain way and it proves to be cost efficient with great results, other surgeons will study it. They no longer need novel or different ways. As information spreads other surgeons do the same thing. That treatment now becomes standardized across the globe.

Same thing is happening to cities. Additionally, often top firms will work on projects globally.

Another interesting example is Hyundai/Kia/Genesis. They hired a lot of German talent. Their car designs are extremely popular now and resemble German cars. Elantra N has been designed under Bierman, who worked for BMW on the M division. Now, the Elantra N is an absolute bargain that can compete with more expensive cars on the track.

You can still choose different colors, finishes, and flourishes.

It's not just that things are now structurally similar, but also homogenized along the design vector.
