I remember moving there, hearing talks about how international Zurich was, and then realizing most of those foreigners were German. :-) It's diverse on paper (and probably to the Swiss), but it's not like it's a cosmopolitan melting pot.
If you exclude neighboring countries Zurich has a foreign born population share of 27% (compared to 18% of Los Angeles). If you only look at the last 10 years Zurich has foreign born non neighboring immigration of 10% (compared to 4% for Los Angeles).
If you only look at intercontinental migration then Los Angeles wins with 14% (compared to 8% of Zurich).
So yes Zurich is less cosmopolitan then LA, but most of it is just because the US has more diverse neighbors.
It's way more diverse than Zurich. Well, if you mean "diverse" as "more brown people" as your comment seems to imply.
Perhaps he's talking about a different kind of homogeneity (one that conventionally falls under the "racism" category)

Do not arm him with arguments
That is absurd for anyone who lives in the Old World. Some of the worst wars in history were fought amongst people whom you wouldn't be able to tell apart in a sauna.
Heck, even Palestinians and Israeli Jews are physically very similar.
"White", "brown" etc. aren't meaningful categories in the Old World, with a few exceptions like South Africa. Most of the Old World is intensely tribal.
But we can look at the opposite part of spectrum - Moldova, poorest country in Europe - 85% of infra is covered by fibre, >90% of population has option to get 1GBit fiber
There are always reasons why something can't be done, just like solving frequent school shooting problem in US
