Just talking about search alternative; DuckDuckGo is my default search engine for over 2 years. It's incredibly good, the only caveat is you need to re-learn how to search. The same way you "changed yourself" initially for google.
Except google didn't need learning, in fact that's part of what made it so much more powerful, they early on dropped support for AND and OR and other boolean keywords which other search engines required to get good results. In fact one of google's early "hidden" successful features was using implicit AND not implicit OR, which had been the de-facto on other search engines, so searching for "gold plates" on other sear…
You certainly did have to learn to use google, you just don't remember it, or remember it selectively. I frequently come across people who ask questions which seem simple to google for, but when they try ask google, they do so incompetently and get bad answers or no answers, because they fundamentally don't get keywords, how other uses of words can override your intended meaning, or how to clarify by adding further phrases, or removing extraneous detail.
