Like the Idea though I’m not a designer! Very good strategy to start your MVP with human powered engine, but I guess eventually you would need to make it AI powered to automate the search if you gain traction and need to scale. It would be too much effort to just do human powered search to just show the results while you are not sure if the users would be interested in any of them! Just to look back in history, Yahoo was a human powered search and google is an AI powered search and only one of them is alive today:)
