LLMs are dead for formal verification. But is treating software correctness as a thermodynamics problem actually mathematically sound?

u/TheDoctorColt2026-03-25r/compsci

What if founders could hedge their bets the way investors do?

u/maninthedarkroom2026-03-25r/Entrepreneur

A lot of businesses stop asking why things are working right when that question matters most
