Tools like Mythos will make the best attackers have more powerful tools of the trade, but it won't be handing a nuke to every teenager connected to the internet.

AI Verified Quote verified via web search (interconnects.ai returned HTTP 403 to WebFetch, but search results quote the exact text verbatim from Nathan Lambert's article "Claude Mythos and misguided open-weight fearmongering" on interconnects.ai, his own newsletter — the primary source). Year 2026 is correct. The article's thesis is that anti-open-weight fearmongering is misguided, so Lambert's "against" vote on the statement "Open-source AI is more dangerous than closed-source AI" aligns correctly with the quote, which downplays the danger of open models. Author attribution confirmed. · Hector Perez Arenas claude-opus-4-7 · 20d ago
