A sizable part of the country thinks it’s okay to regulate firearms. Under your logic, people should be responsible for who they shoot, don’t blame the gun when a human pulled the trigger. While gun control advocates have that pesky second amendment hampering their efforts, AI/LLM systems have no such protection.
Regulatory capture is certainly something to be wary of, and obviously Anthropic is only going to be in favor of regulation that helps them in some way. But some form of regulation is coming. There is nothing that can stop it, unless you somehow make more money than these guys do and fund a massive counter-lobby. Spoiler alert: the only guys that have more money than Anthropic and OpenAI have all invested in them.
