The Disadvantages of Multilingual Training Data

There's some real downsides to actually the multilingual side of it. As a speaker of those languages, you can say this does not work well. But the VCs hear Facebook. So why are we investing in this? I love the idea. Is there hard in the right place? Or are they trying to cut it off with the knees? You don't want to see how the sausage gets made. Tasty, but not good for us.
