Fwiw:

The last paper I saw posted on hackernews from Gil Kalai included a few explicit predictions about what would be impossible in quantum error correction.

This was a paper from a few years back.

The problem is that now Google has published results which imply that some Kalai's predictions turned out false.

The paper in question is Google's recent "below threshold"/"beyond break-even" QEC paper. I believe Kalai was predicting below threshold QEC to be impossible IIRC, among other things.

Not sure if Kalai has responded or updated his predictions, I haven't been following him closely.
