the money really is the crux of the issue, too. if you take as a given that consumers won't pay for a service they can get for free, then you're kind of in a bind creating an unopinionated search - if you're truly objective, and reflecting the underlying value of each link faithfully, who do you charge?
I hope the project of improving on DuckDuckGo is successful though, and some of the other proposals in the article sound promising to me.
In the future I would like to see an open source search engine 'paid for' using some combination of homomorphic encryption, blockchain and Tor-style technologies to trade bandwidth and processing power with its userbase in exchange for search results and other services, but I don't have the expertise to assess how feasible that might be.
