Most people use, and want to continue using AI while searching for things. When you want a quick answer to a simple question, having Quick Answer there is great, as you don't have to parse everything, just check the citations to see if it's actually correct.
As for News, it has revolutionized the way I get information about events in the world. The ability to filter out things from my feed I don't care for, combined with the multi-faceted approach of its reporting (often fetching a wide variety of sources) makes it far more resistant to bias than most other sites. Though I do have to mention that no news site will ever be perfectly biased to your taste, so its in truth up to you to analyse all news with caution, which is what I do, even for sites I normally trust.
Assistant and Summerizer are both just incredible. As someone who used to ask ChatGPT, Claude, and Perplexity for explanations during research, having all AI models aggregated and pre-prompted using Kagi's own backend wizardry is great. Summerizer has NEVER failed me, despite having used it probably hundreds of times by now. Assistant can get wanky on lower quality models, but again, if you use Assistants without checking important facts, then that's your fault, not Kagi's.
I do wanna make it clear though that what you're suggesting seems important to you, but useless to most, and redundant for most of the minority you're in. If you don't wanna use AI: Don't. That's it. But Kagi will continue to serve AI users, because 95% of people use AI to search. A killswitch is just virtue signalling: quick answer can be turned off, AI can be filtered from search, and you can always just opt to not use Assistant/Translate/News/Summarizer.
And mind you, Kagi is not a browser, they're a search engine; their browser, Orion, does not include ANY AI built in. That should tell you everything you need to know about their relation to AI security. Unlike base Firefox, Orion does not even begin to open the gates for the prompt hacking nightmares of yore, and Kagi Assistant itself also compartmentalizes your chats: No two chats ever feed into one-another, making their solution far safer to use than standard sites.
The fact that Kagi doesn't follow a tiny minority of its vehemently anti-AI userbase is actually a big source of trust for me: It means that Kagi won't bow down to small but loud groups, rather, they take their wider userbase into account when making decisions.
