The risks need to be discussed and understood, along with the benefits, and publicly. That's the only sensible way forward. Denying that the technology is here already and pretending it can be "paused" doesn't assist in alleviating their concerns.
It's absurd to think any of it can be put back inside the box it came out of. Now that it is here, how best to mitigate any bad sides it may have? Simple, continue to develop it - as it will be the only viable source of effective counter-measures.
