> to ensure children are not exposed to harmful content.

Strong claim. I like the idea, but wish they were more realistic about what they can provide. If you ever get a Reddit result you're likely one click away from harmful content.

That said, I like the lenses applied in this case. It may be the best we can get today in terms of search filtering.

Or they head to Wikipedia, search for "fish" and end up on the Albert Fish page.

I think aiming for better rather than perfect is the best option, as you said. As long as it's framed in this way, and not as an ideal option to let your impressionable child loose on the internet.

Kagi lets you block results for various sites you don’t like, if sites like Reddit are of concern.

I get it, but that wasn't the point. There's lots of sites which will have your result and harmful content right next to each other. Reddit is known for being a collection of very unrelated subreddits, but you won't know every site like that. Kagi writes "ensures", but they can't really ensure anything here. They'll have the best guess of the first click being safe and even that is often problematic (what kind of safe?, for what age?).
