Certainly transparency is key. Is it up to government only? No, absolutely not. The government plays a very important role once this technology gets to a point where you're ready to put it into the population. Then, yes, you have a regulatory responsibility to take a look at that, and that's really important.
However, ultimately what's going to put everybody's minds at ease is science. It has to be science-based. If you have the testing to show that it's safe and efficacious, just as you do with drugs, it's the same concept with these types of changes. If the science backs it up, that has to give people reassurance. I don't know how else to do it.
If we live our lives in fear of what may happen, I'm not so sure I'm going to drink this water. I could tell you that eating broken glass may make you better. Science tells me that eating broken glass is not good for me, but it might make you better. I don't know. However, you're not going to go out and eat broken glass just because it may make you better.
It's the same thing the other way around. Science tells us that it's all safe. If the science is rigorous and solid, I think we should go with the science.
