You would be surprised. Humans will do human things like be extremely inconsistent, ignore warnings (if they are not enforced as errors), skip steps because they are lazy (devs often chose to skip our pre-push hooks and preferred to run in CI and babysit the PR).

Agents can also do all of those things, but they are generally more compliant to instruction.

That’s an assertion with no evidence that doesn’t match my experience.

Agents require far stricter guardrails than humans. Without linters, tests, static analysis, oracles etc… no agent can create a large program.

Even if you’re correct, you just build those checks into CI so that neither humans nor agents can skip them.
