Here's our take.

Formal Proofs

Nice Pick

Developers should learn formal proofs when working on safety-critical systems (e

Pros

• g
• Related to: proof-assistants, formal-verification

Cons

• Specific tradeoffs depend on your use case

Informal Proofs

Developers should learn informal proofs to improve their ability to reason about code correctness, algorithm efficiency, and system design, especially in fields like software engineering, cryptography, and theoretical computer science

Pros

• They are essential for writing bug-free code, optimizing performance, and communicating technical decisions in code reviews or documentation, as they provide a structured way to validate logic without the overhead of full formal verification
• Related to: formal-verification, algorithm-analysis

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Formal Proofs if: You want g and can live with specific tradeoffs depend on your use case.

Use Informal Proofs if: You prioritize they are essential for writing bug-free code, optimizing performance, and communicating technical decisions in code reviews or documentation, as they provide a structured way to validate logic without the overhead of full formal verification over what Formal Proofs offers.

The Bottom Line

Formal Proofs wins

Developers should learn formal proofs when working on safety-critical systems (e
