I don't have the time at the moment to read the paper, but I did RTFA, which unfortunately tends to point to the paper instead of summarizing its examples ("The authors highlight several examples of harm caused to both workers and users." [end of paragraph]).

Even at the end, I still don't understand what the TESCREAL bundle subscribers expect AGI to accomplish. Replace the labor of "undesirable" humans? Or is it meant to be a transhumanist intelligence aid?

In reality, these issues do not persist simply because of a lack of intelligence or ability. Solving them requires collaboration and systemic change on an unprecedented level.

Spot on.

We already grossly overproduce food and have grown food in adverse conditions for at least a century, I'd guess millennia, and we know why it isn't distributed adequately (spoiler: profit-oriented economy). We already know major causes of climate change and have the technology to replace them. In fact, some of the most industrial countries on Earth have already plateaued certain important emissions. We know why many technological advances are antagonized (spoiler: profit-oriented political economy). The knowledge has been known for a century and decades respectively. I know this is expanding on a tangential remark, but it's important to emphasise that we know the path forward, we know who stands in the way, and we have known for a long time.
