Multiculturalism should be the means, but not the ends. The goal is to find max diversity of ideas, if you can achieve that by pulling in people from different cultures, fine, just don't make it your goal. After all, people from different cultures can think the same.

Is maximising diversity of ideas really the goal? Good ideas are worth a lot, bad ideas have zero value or negative value.

Diversity of ideas can be a good thing, but it can also mean diluting good ideas with ones that are valueless or actively harmful.
