I drilled down on this with Tom. He thinks that it might not have happened without Claude Code, but Claude was used to organize all of the symbols, and to run I think it was 100,000 simulations to assess whether or not he had an actual insight, or if he just randomly got lucky. Claude did NOT crack the code. Significant supporting role though.
So Claude Code was used to generate software that ran simulations? I don't think LLMs in and of themselves can execute simulations, esp. a specific, non-single digit count like 100k.
