So, vulnerable prototyping with no duty to security until incidents happen, which you will then iteratively patch in 'fixes' as an afterthought while increasing its risk until a government regulation steps in?
Black Swan events are not a "myth".
AI tech has new risks to manage.
Every new technology is developed and deployed the same way:
You make a prototype, try it at a small scale, make limited deployment, fix the problems, make it safer, and then deploy it more widely.
At that point, governments regulate it and establish safety standards.
