No, a human could do (and have, many many many times, see like half of molecular biology) this as well. If anything this will help with vaccine development.
Edit: I'm a PhD biochemist that has done a fair bit of virus modification. Love the downvotes. Never change HN. ¯\_(ツ)_/¯
I agree with you. I favor the view that humans are generally morally good when taken on the whole. There already exists the technology for ne'er-do-wells to engineer viruses and unleash them on the world. But I submit that A) there aren't many people who want to do that in the first place; and B) there's a vanishingly small amount of people who want to work with those people to help them achieve it.
That doesn’t invalidate the point, you’re just saying it’s already a risk
Same reason it couldn't be a problem to sell aerosolized anthrax at the hardware store. Humans have (many many times) made aerosolized anthrax. Can't see any conceivable problem with more people having access to it.
