* I won't use a different search engine for programmers stuff vs everything else. So while this might be targeted toward software developers I can't see myself using it unless it can handle normal searches.
* UI/UX - I hate the progress bar, I'm not sure at all what it's telling me as there are results shown while it's still completing. The results are way too spaced out. On my 27" 2K screen I can only see 3 results, the search bar takes up way too much space and there is way too much padding on the results. Don't move the DOM on me, removing the progress bar is jarring as is "Was this answer helpful?" popping in, I'm here for results, not to train your ML.
* Trackers - Using the default installs of Privacy Badger and uBlock Origin meant no results ever loaded. I'm not sure what was being blocked that caused the issue but cookies from bing [0] and a request to cloudflareinsights.com [1] should not hamper showing results.
Search is a tool and one that I need to be quick, simple, and informationally dense. This checks almost none of those boxes. I'm even open to using a different search engine (I semi-recently switched from Google to Ecosia and it's been near-seamless), but I don't see any "pro" to using this engine and I see a ton of "cons".

EDIT: I did a few more searches because I realized I wasn't getting the "info box"/ML results on my first few searches and I wanted to be fair. Sorry but that made me dislike this even more. I really, really hate content moving out from under me. My eyes start reading one of the 3 results that was shown then they got pushed down for another overly-padded box that tried to "answer" my question. The results were worse than "grab the selected answer from the first SO that matches this query". Maybe it would be better if that info was shown off to the side and didn't move the results when it loaded in but again, I didn't find it useful in the queries where it showed up.
EDIT2: I posted a follow up comment about what, specifically, I think should be changed: https://news.ycombinator.com/item?id=32005841
