Bob Boyd died. At some time they all do. As you can see several of them already did. What you see is in Finnish. This example of disambiguation could have been in any language.
That is very much the point. With Reasonator we disambiguate in any language.
We can when we ignore the effort that goes in adding descriptions. Many of these descriptions are out of date, incomplete or just not available. I do not fix descriptions; I prefer to fix automated descriptions. I do this by adding missing statements. In this way the automated description is fixed in any language.
When people add descriptions with a bot, they could have added statements in stead. It would have been useful and when all the effort had gone into adding statements, Wikidata would be in much better shape.
As it is, there is no convincing argument for having fixed descriptions. They suck. They are mono-lingual where Wikidata is not.
