web3 protocol devs - consider integrating security testing tooling into your CI and not relying solely on security audits
security researchers - consider building proper security tooling, rather than focus solely on providing security services and posting another audit
Controversial take: Tooling is far more impactful for security than teaching/writing.
People use stuff that makes their life easier. Low-skill devs may not read about the safe way to handle ERC4626 rounding, but they will grab OZ's code all day long.

Security should be a crowdsourced effort, not a centralized one.
Traditional security reviews, while important, can't replace the feedback from a wide pool of users.
The power to scour, detect, and identify potential threats lies in a collective.
