That is very true, especially when it comes to any administrative task. However I’d argue that these jobs are less likely to be replaced, as these jobs are born out of a system that is favoring bureaucracy for the sake of bureaucracy over efficiency. Challenging that system would result in a shift in the power dynamics, often towards subordinates, which, of course, wouldn’t really be accepted by leading positions.
I do think it’s worth the money however, especially since it allows you to cutomize your search results by white-/blacklisting sites and making certain sites rank higher or lower based on your direct feedback. Plus, I like their approach to openness and considerations on how to improve searching without bogging down the standard search.
