Interesting. While GPT3 has been programmed to not recommend even an aspirin for a headache – because that's medical – it'll happily give you this rappelling advice that could get you killed. None of the rappel devices mentioned are suitable for really long descents, as rope weight will get them stuck, and even if you manage to get them unstuck, you'll overheat the rope.

(a late friend of mine was part of the team that did the first descent of the world's longest rappel, 1250m down Mount Thor)
