Much of our work is still manual (hand holding the AI) but our automated harnesses are getting better at the same time.

BTC news: Some Bitcoin developers say they're finding a critical bug every hour
A volunteer group running AI models against bitcoin codebases says it is averaging roughly one critical bug per hour per person, at about $10,000 a day in compute.
AI scanning uncovered 4,962 security flaws (85 critical) in 390 Bitcoin projects within 24 hours, overwhelming maintainers. Attack leverage equalized: Anthropic's model found 27-year exploits for under $50, forcing crypto to rethink security architecture investment.
