A key concern I've consistently had regarding formal verification systems is: how does one confirm the accuracy of the verifier itself?<p>This issue appears to present an intrinsically unsolvable problem, implying that a formally verified system could still contain bugs due to potential issues in the verification software.<p>While this perspective doesn't necessarily render formal verification impractical, it does introduce certain caveats that, in my experience, are not frequently addressed in discussions about these systems.
