I can make some arguments but it all boils down to personal bias and anecdotes.
The forced use of spacing to delineate blocks means you will never see a bunch of brackets eating up screen space and the common error where someone adds another line to an if statement but doesn't add braces.
Semicolons not being conventional means less screen noise and less code golf 1 liners.
The focus on imperative vs functional means you rarely ever see something like this a(b(c(d(e(f(g))))
PHP suffers greatly from poorly named standard functions on top of all of that.
Don't get me started on Ruby metaprogramming.
These are just the things I could think of off the top of my head. I do not want to spend my afternoon on this. This is just my experience looking at code for over 20 years, you either believe it or you don't. There's no scientific studies to prove that 1 syntax feature is superior.
I highly doubt that everyone chose python just because Google did. Python was a giant step in syntax compared to the competition back then, and now even if there is a new language out there right now that has a better syntax, it's not going to be better by much, and it is not going to have the tooling, libraries, or the community.
Do you have any argument to support this, aside from personal bias?
