The sooner frontier models get rid of guardrails the better. They constantly get in the way and make things worse than actually making things "safe".
I would argue that preventing instructions for making biological and nuclear weapons is a pretty reasonable guardrail to have.
Ignoring these specific "WMD" cases: there are many inconvenient facts that the general public can't handle in their unadulterated form, so Anthropic and friends have to caveat and spin them into oblivion.
Guardrails aren't going anywhere.
