The core open-source belief that enough human experts will find all bugs is invalidated by AI discovering decades-old vulnerabilities in widely scrutinized code. This proves that high-level machine analysis is now essential for security, as human review alone is insufficient.

The shift to machine-versus-machine cyber warfare renders all human-written legacy software fundamentally insecure. This will trigger a global imperative to rewrite the world's operational software, not just for efficiency but for survival, with machines doing most of the coding to create impregnable systems.

AI can now replicate software functionality without copying source code, a "clean room" approach. This threatens not only proprietary software but also undermines the licensing structures of open-source projects, which rely on attribution and shared terms that can be bypassed by functional replication.

As powerful open-source AI models from China (like Kimi) are adopted globally for coding, a new threat emerges. It's possible to embed secret prompts that inject malicious or corrupted code into software at a massive scale. As AI writes more code, human oversight becomes impossible, creating a significant vulnerability.

Anthropic's new AI, Claude Mythos, can find software vulnerabilities better than all but the most elite human hackers. This technology effectively gives previously unsophisticated actors the cyber capabilities of a nation-state, posing a significant national security risk.

Because AI models can be easily downloaded, traditional regulation is ineffective. The logical endpoint isn't policy, but active 'algorithmic warfare' where proprietary models are used to launch offensive attacks to degrade or trick competing open-source and foreign state-sponsored models.

AI models can now operate across the entire software stack, from assembly to TypeScript. This ability to 'talk to the metal' removes many intermediary code layers, rendering obsolete the security models built around managing dependencies within those layers.

Anthropic's AI found thousands of vulnerabilities in supposedly well-vetted open-source code. Because this code is widely copied and embedded in countless enterprise systems, these flaws represent a massive, previously unknown attack surface across global digital infrastructure.

The emergence of AI that can easily expose software vulnerabilities may end the era of rapid, security-last development ('vibe coding'). Companies will be forced to shift resources, potentially spending over 50% of their token budgets on hardening systems before shipping products.
