Let's not forget that as of now most models are like game cartridges i.e. they need a 'host' to run i.e. llama.cpp - they're not executable code by themselves.
I could see an argument for a security review prior to integrating a model into a highly sensitive industry/agency, but that is standard for any software.
It's certainly not an argument for banning open models because US AI corps don't want to compete with them.
I agree this is science fiction-y, but given the pace of progress I don't think it's so easy to dismiss.
