We get our expectations from fiction. AIs in shows like Star Trek are precise and accurate - the perfect complement to the unreliability of humans. That’s what we want.
However if the AI is the same smart as the most dumb human or human with mental disability would we then consider those humans as no intelligent at all or not qualifying as homo sapiens anymore?
If AI can be the same as good as even 'dumb' human it's already a big achievement because can still provide some value and because AI can be scaled so you can still have billions of dumb AIs - already millions of users are interacting with chatGPT daily
