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.
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).
But we should also note that HN users are the "spearhead" of adoption curve and if there is ever any meaningful alternative to Google, just by the virtue of HN users adopting it, could mean strong propagation in their social circle - the less tech savvy family members, friends and work.
