"The next Google can’t just be an input box that spits out links" I think one strong contributing factor to Google's success is its simplicity. All the listed competitors add a lot of complexity imho. While all the customization buttons, knobs, lenses, meta crawling, code generation features etc might add some value for the advanced and technically skilled user, it provides rather little value for the average user wh…
I work for Neeva, and this is a big part of why I left Google to join Neeva. There has to be a better experience, and it doesn't start from another business that works just like Google. It has to be a different kind of business. Neeva does not make money from showing you ads, so it can provide a different search experience... a simpler search experience, like the original google even, but it can go further...
With the Neeva app for example as you start typing in the URL bar, it will take your input as search suggestions (just as any other browser + search engine would) but instead of just showing you completed search suggestion, Neeva will show you the results from running those searches inline. The idea being that maybe those results will be helpful to you and make it so you don't even need to go to the search results page. You can just take the result right there from the URL bar suggestions drop down. Saves you time. Simpler.
Stuff like that. There's a swim lane of innovation and ideas on how searching and browsing can be better that is just really hard for Google to build, even though many of these ideas are thought of inside the walls of Google. They just can't ship them if they are stuck being beholden to their search ads model.
Another great example... ever wonder why Google isn't working to make it so Chrome doesn't have a million tabs at the top of your browser? It gets to the point where it is hard to get back to what you were doing. Me, I just end up closing the tabs, declaring tab bankruptcy. Google is okay with that because it means I have to search again. The Chrome team wants to fix this but it is hard to do so as it would result in people searching less often!
Again, just means there is opportunity for a simpler better experience to be had and Google won't be the ones creating it.
