So much of human life is tied to the reward of the sense of accomplishment, and AI threatens that in a meaningful way. From large things, like seeing a piece of software you built ship and get used, or seeing your child graduate from college after years of hard work raising them, to the small things, like even eating a delicious meal you cooked yourself.
When machines are not only offering to solve problems and perform actions for us, but are reading are thoughts and doing everything for us before we even make an attempt, I worry that sense of accomplishment will become ever less frequent.
And while we can compensate for machines taking jobs through, eg, universal basic income or the like, how we can solve for machines replacing struggle, perseverance, and accomplishment is still very much TBD.
