The main problem is that Instance Of is not being used properly sometimes. In general, wrong classifications across Wikidata lead to weird assumptions.

Better documentation, and even helper rules to help prevent wrong classifications is what is needed and its forthcoming.

Lydia has mentioned that these kinds of problems will eventually become less and less as the Roadmap features eventually land into production.

I am looking forward to next year, and the year after, to see the quality improve.
