Looking at the results and the prompt, I would tweak the prompt to

* ignore comments that do not speculate on something that was unknown or had not achieved consensus as of the date of yyyy-mm-dd

* at the same time, exclude speculations for which there still isn’t a definitive answer or consensus today

* ignore comments that speculate on minor details or are stating a preference/opinion on a subjective matter

* it is ok to generate an empty list of users for a thread if there are no comments meeting the speculation requirements laid out above

* etc

Agreed. I feel like it's more just a collection of good comments. It doesn't surprise me to see tptacek, patio11, etc there. I think the "prediction" aspect is under weighted.

But it reminds me that I miss Manishearth's comments! What ever happened to him? I recall him being a big rust contributor. I'd think he'd be all over the place, with rust's adoption since then. I also liked tokenadult. interesting blast from the past.

Good points. To summarize: for a given comment, one presumably must downselect to the ones that can reasonably be interpreted as forecasts. I see some indicators that the creator of the project (despite his amazing reputation) skated over this part.

You would also need to exclude “predictions” for things which already happened at the time they were predicted.
