The community was deeply divided over Cal.com’s decision to abandon open-source for its core codebase, citing the reality that AI vulnerability scanners have given attackers the blueprints to generate working exploits in hours. This sparked a fierce defense of the GPL from Discourse, arguing that hiding code is a business decision and true defense requires an open ecosystem where defenders can run the exact same LLM scanners. The underlying fear across these threads is that cybersecurity is transitioning into a “proof of work” token lottery, where defenders and open-source maintainers must simply outspend attackers using highly capable models like Anthropic’s “Mythos”.

The future of everything is lies, I guess: Where do we go from here? Kyle Kingsbury (Aphyr) dropped a blistering, comprehensive critique of the generative AI ecosystem, arguing that the technology is fundamentally eroding our information ecology and personal metis. He is urging developers to form labor unions, refuse to use LLMs, and even quit their jobs at major AI labs to slow down the deployment of unpredictable models.
