I liked the original autotldr bot on Reddit. The one here though seems to be producing a large summary instead of just TL;DR.
Here's an example: https://lemmings.world/comment/920986
This comment takes up most of the screen space on my mobile device. I don't consider this to be a TL;DR. At this rate, I'd opt to just read the article in question instead.
The other problem is that lengthy TL;DRs like this obstruct comments, making it annoying to scroll past for those of who are on mobile devices. I could block the bot of course, but I don't want to - I do want a legit TL;DR, not a reworded article.
Here's my attempt at generating a TL;DR of the mentioned article, using ChatGPT:
Two manuscripts published on the arXiv pre-peer-review repository claim to have synthesized a room-temperature superconductor, LK-99. This superconductor is a variation of lead apatite, and allegedly operates not only at room temperature but also above water's boiling point, at regular pressures. The synthesis process is complex, yielding potential variations in the final product. Early attempts to reproduce these findings have shown mixed results, adding to the intrigue and uncertainty surrounding the material's properties. While these claims could potentially revolutionize the field, their validation would give rise to further challenges about how to transform this material into a practical, high-current-carrying form. The upcoming period is likely to see intense activity from labs worldwide in their efforts to corroborate these results, which could significantly accelerate the emergence of a scientific consensus.
IMO, this is what a TL;DR should look like - a single paragraph and under 150 words.
