Not really. When I say meaningful alternative to Google, I mean something that is same or less effort for an average user, not more.
Ideally a perfect search engine is simple and easy to use in the default mode, but can uncover an advanced mode with a few clicks (for example ability to ban sites in results, just to give an example. This is currently lacking in Google and a solid source of advanced users' frustration).
You're essentially proposing that less tech savvy users switch to something that requires more effort from them. Even if the results are 10x better--hell! they could be hand picked--it won't convince the average user to take a path of more resistance.
That said, I would love to see a competent competitor enter the marketplace--there already are a few. But I have a feeling we'll be heading back to a system of more niche/focused search engines in the future.
