It is not obvious. If it were, it would be forbidden from day one, everywhere.
You are putting way too much faith in governing bodies. In reality, governments often need significant pressure before ruling on something "obvious"
Oh, I did mean that literal. It just is not obvious how to handle llm systems and their capabilities. It is a new concept. Anyone claiming it is obivous just has their own opinion and tries to convince other people with non arguments. It is a type of fallacy. Propably this one https://en.wikipedia.org/wiki/Argument_from_incredulity
But we need real arguments and reasoning to deal with llm in the future. The tech won't go away. And arguments of an ethical nature can be overcome and what then? Arguments that machines take human jobs? Those never worked.
