Speed of light is not the bottleneck in reaching 1000ms search response time anywhere on earth. Calling it a speed-of-light limitation does a disservice to your point, which really is that querying many peers for search results is slow, for reasons that have nothing to do with the speed of light.

That some video content may not reflect its supposed category or title is not a new problem, is it?
