But before all this language technology can be applied, it is important to get the facts. Fact is that all the subjects of all the Wikipedias can be found on Wikidata. Many statements have already been made about these subjects. It is good fun to spend time adding statements.
With the "reasonator" as seen above you find a nice presentation of what these statements indicate about a person. Providing a nice presentation that is available in participating languages is probably the first development challenge. Getting "all" the facts is probably the first community challenge.
