Don't take that advice as discouragement to start.
Google did have to engineer a giant distributed system to provide the search results we get. There are articles that talked about how they just had motherboards connected to hard drives laying on anti-static pads filling rooms in buildings. The racks and cabinets didn't make sense for them.
Today we take for granted software stacks like lucene. Nothing like that existed when Google moved into the space.
So yeah, 15-20 years ago internet search was a really difficult problem. Now, the sheer volume of research available which specifically addresses the problem space of a trusted decentralized search, to me, means that a solution is imminent.
You could be the person that puts all the research blocks in the right order and launches a successful project.
