Sorry to hear that you're so negative. It's quite obvious that this is not
currently used in Wikipedia, but is presented everywhere as a novelty
that has not been around for 20 or 30 years.

Thanks! This answers my question. It's particularly interesting to read
the talk page to the plan. Part of the problem is that "word embedding"
and "vector search" are not mentioned there, but a vector search could
have found the "ML-enabled natural language search" that is mentioned.
If and when this is tried, we will need to evaluate how well it works for
various languages.
