> Humans do a remarkable job of dealing with ambiguity, almost to the point where the problem is unnoticeable;
Isn't this because we have knowledge of the world?
The sentence "Alice drove down the street in her car" won't ever be parsed as "the street is in the car" by a human because we know that streets don't go in cars.
Computers won't ever solve this without having a larger knowledge base to compare the parsed sentences and remove the ridiculous outputs.
