- Praise: Spending $100k in tokens in a week is an impressive feat even with massive parallelization, showcasing the power of Claude's capabilities in cryptographic research.
- Praise: The collaborative approach led to significant breakthroughs in discovering vulnerabilities, highlighting the potential of multi-agent workflows in AI applications.
- Praise: The HAWK attack's ability to halve the effective key length is a noteworthy achievement in cryptographic research, raising questions about future standards.
- Concern: The obsession with 'prompt engineering' feels misguided when the software still struggles to follow instructions effectively, pointing to fundamental limitations in LLMs.
- Concern: There's a growing tech aristocracy with access to powerful AI tools that could widen the gap between those who can afford extensive API usage and the average user.
