Some services (like Google Search) are about returning a set of results that may possibly be right. Algorithms are undoubtedly brilliant in that context. When you want a single authoritative answer the gaps in datasets become much more obvious. To answer that type of question you either need better data (with cost and privacy concerns), or more human input. There are lots of problems that algorithm centred companies are not good at solving and it is very annoying that we are so reliant on them.
