There are plenty of problems that have technical solutions, or might have technical solutions. Diseases of all sorts, disabilities, pollution, climate change, incidentally complicated bureaucracy. Although you can gesture that these have a social component, even for that, the social component becomes much easier to address if the cost of addressing it goes down.

To say nothing of how ubiquitous manufacturing automation would make material goods accessible to a much broader range of people (though, you could argue that material goods are today effectively universally accessible, and I wouldn't disagree).

Climate change is a good counter example i think, because we mostly know the solutions (Gates book breaks it down) but lack the political and social organization to execute.

But generally agree, i just think the current counter cultural movement towards progress on such fronts is a good example of how overcoming this is more important than technological solutions as such. Unless AGI has a technical solution for that too (it might!).
