AI-assisted vulnerability discovery appears to scale with token/compute spending (per the UK AI Safety Institute evaluation of Claude Mythos and Drew Breunig’s reading), implying defenders could harden systems by outspending attackers in an ongoing, token-budgeted “proof-of-work” race—shifting security from one-time audits to recurring AI-powered review budgets.

AI-driven security can raise the economic value of open-source software because AI-based hardening costs can be amortized across many users, making shared security investment in widely used libraries more attractive than duplicating reviews for bespoke code.
