It is at least a handy retard barometer. You should always be wary of who trusts what is basically a patchwork glorified chatbot, a digital midwit that openly lies to you because making shit up that smooth brained investors can be fooled by gets you more contracts than having the thing honestly answer and give a "I don't know/I don't have enough data on that subject" response when it's got nothing.
Add to that, the super majority of them are coded and trained by a revolving door mix of true believer tech bro dorks who thought VR crypto casinos were the future, dyed in the wool bugmen reddit admins and wiki jannies, troons named lilith/loona who learned to code over a particularly grueling two day weekend and a gaggle of the finest lowest bidder saars money can buy.
"AI document summary" too should be looked at disdainfully, as it's overly trusting the worst people backed by the dumbest empty suits to tell you second and third hand information passed through a series of no no word and concept filters that you could have read your own goddamn self instead of getting regurgitated and pre-censored and mangled in the form of a bite sized bedtime story.
