That said, other humans can and will put AI to use in ways that don't benefit humanity. It's actually already happening - newsfeeds waste hours of people's lives and attention; give teens low self esteem etc etc. and guess what. Society is adjusting - governments via legislation, device makers via screen time limits, communities by spreading the word and raising awareness
Smart AI wielded by people without your best interests in mind may be tough to counter; but you don't have to do it alone: humanity is getting wise to the threat. We don't have great tools but it'd be against the grain of history to assume we won't come up with them in time. Can't give specifics - as they say, predictions are hard, especially about the future..
We've made it through bigger more violent upheavals and we'll make it through this.
