I feel like 23&me is literally only useful/interesting to white people because they can see which one of the 50 European countries they have ties to.
It's not that useful for me. I've had friends do it and get 99.97% Chinese or Indian.
Amazing, I could have told you that for free.
I'm not familiar with the kinds of ancestry information they can provide, but why would that only apply to white people? Why not also, say, people with African heritage and which of the African countries they have ties to?
I find the health tests to be more interesting than the ancestry, though it was a bit scary though having to click through all the warnings to get to the results.
it's ultimately probably not important, but I would think that it's at least something to be curious about.
