Nobody really thinks that AI is useless anymore. We disagree on timelines, we disagree on how useful it will be, but the extremes are not between useful and useless (although some people believe it will not change anything, but pretty fringe). The real extremes here are "evil god AGI" and "benevolent god AGI". This piece takes the road where they say: it's pretty powerful/useful, but it's not a godlike something because it's not everywhere, all the time, at once. It will change the world, but over a pretty long timespan and it will feel like normal technology. It will be used for evil and good.
