Nobody is claiming the results are false.
We're saying look critically at the claims for how it was done, that it only cost $2000, etc. it would be extremely easy to run 100 sessions that failed, each costing ~$2000, and then just publishing an article about the one that succeeded, for example.
This goes double since it's an internal secret model (Astra) so nobody else can verify the results.
Would this be your reaction if OpenAI also solved millennium problems? The point we are trying to make is that the significance of this news is much larger than the skepticism you are providing.
