I agree, but isn't that how things are. Fire is a great hazard, and can cause a huge disaster. Thousands got killed from it. Same goes with nuclear energy. Does this stop us from using them? NO! Because we see the tremendous value it can provide, and look at the risk vs reward. Same goes with editing human embryos. Virus, Bacteria, can create generations in ~30 minutes. They're able to adapt to my medicines, and antibodies. We need genetic changes to outgrow them. There will surely be many mistakes initially. But we need to offset them with through trials, and testing. Not by an outright ban.
