Cryptographer Matthew Green weighs in on the ongoing Marcus drama: he substantively disagrees with Marcus on AI capabilities but values the argument itself.

His real concern is that a 250K-follower account is shouting down people who seriously consider that open-weight models might shift the offense/defense balance in cybersecurity — behavior he says harms the open discourse the industry needs right now. He argues someone with his reach and independence from vuln-research peer pressure should call it out.

The thread captures ongoing tension between the infosec and AI communities over whether LLMs can realistically develop and fire exploits.
