I hate to be the bearer of bad news, but the discovery of CRISPR a few years ago means that gene drives are more accessible than ever. I'm not sure if it will be feasible to defend against them at all for the foreseeable future.

All the more reasons for being able to deploy swift and heavy biosafety measures at a moment's notice. But I didn't want to go into that territory, because a) I don't want to sound too alarmist, and b) I'm not very confident about what is vs. what isn't possible with CRISPR-based workflows in terms of bioweapons.
