> machines like Parsey McParseFace can now accurately parse human universal grammar. unambiguous parsing was a big feature of lojban, so it's lost a major selling point.

Slow down there ... Most linguists (or a substantial minority) do not subscribe to the theoretical idea of universal grammar. Parsey McParseFace is only an incremental improvement in decades of statistical parsing. The problem of natural language understanding remains largely unsolved. Like other deep learning models, it is not hard to come up with adversarial examples that will confuse the parser but not any competent human language user. The parser is only as good as the data it is trained on; this data is expensive to acquire but there is never enough. Additionally there are a myriad other kinds of ambiguity in language beyond the sentence-level syntactic ambiguity which is resolved by a statistical parser such as Parsey McParseFace.

In my opinion Lojban provides a good illustration of just how hard it is to remove ambiguity from human language.
