The potential alleviation of suffering is great, the potential suffering is also great. There’s a reason nobody gene edits humans (with one notable exception…), and it’s not because it’s hard to do, I’ll tell you that much.
It’s at least somewhat reassuring that all scientists (except the one notable exception who shall not be named) is taking their time to really understand the implications of the technology.
Gene editing is, like many technologies, a tool, and it must be subject to guidelines and regulations to ensure that it can only be used for good. That much, everyone agrees on. The question that people still need to grapple with is where the line is drawn between acceptable and unacceptable editing.
I will also point out that there are ways to influence your biology without messing with your DNA. And similarly many ways to mess with your DNA that do not carry over to the next generation. All of these fall under the umbrella of gene editing but don’t fit the popular concept of gene editing (germline editing). These techniques are much less ethically ambiguous and many are already being used to help people. Here’s a fun video where a guy transduces a gene into himself to cure his lactose intolerance. It’s gene editing by technical definitions but not the type of gene editing that you’re probably thinking of.




Shadowing is very important for jobs where the outcome of failure is potentially harmful or costly. Biological research is done almost exclusively through an apprenticeship-like training system, and part of that system is that you shadow a mentor when you start. (You’ll also continue to work closely with your mentor so that they can continue to supervise you personally for a long while before you’re allowed to work on your own)
My understanding is that hospital or medical work is pretty similar in that regard
