Yes. Duck Duck Go is easily turned off or on as you want.

Interestingly I have seen information from this site show up in Google AI summaries.

Soon, your vocabulary will be: 'bah bah'.  Call me a dinosaur, but it is an insult to have too much technology doing thinking we always did for ourselves. We called it learned intelligence not artificial.

AI is an upcoming threat to the human thought process and a lazy means to circumvent the ladders of research and learning. Right now I can't see a way that our and other civilizations can possibly avoid  ESI ( electronically stored information ) or AI. This cyber animal has no limits or maximum appetite that we can fathom. Hate to sound so doomsday but it's here and moving in leaps and bounds. 

I can certainly see specific and limited bounds for this technology but I can also see the old problem with ' bad info in = bad info out '. So how does AI ascertain the accuracy of their source data ? From what I've found they don't warrant accuracy but develop their findings predominantly on reasonably predictable possibilities already in the public domain. That end users must fact check everything. 

There has already been numerous instances where AI has rendered erroneous conclusions and assessments apparently the result of faulty input. With the pool of expertise here then AI better stay on its toes. I've found AI wrong a couple of times and that's just one person in limited fields.
