Linguistics

I'd take claims from Microsoft with heavy scepticism; they tend to heavily overrate the capabilities of their own software. However, if it is true and accurate, it's an amazing development, and it might solve problems in the video, like:

• The trophy doesn't fit in the bag because it₁ is too big.
• The trophy doesn't fit in the bag because it₂ is too small.

For us humans it's trivial to disambiguate it₁ as the trophy and it₂ as the bag, because we know stuff like "objects only fit in containers bigger than themselves". Algorithms usually don't.
