Hi ex3t1524, and thanks for the question! This isn’t really my area of expertise, so I don’t really know the answer to it. I think we’re probably not at an advanced enough stage to do it properly yet. But it is important to think about the ethical issues of doing something like this – in other words, even if we could do it, would it be the right thing to do? It might be very dangerous for the people and animals involved. That’s why it’s important for scientists to spend lots of time understanding what it is that they’re actually trying to do, and whether it will ultimately benefit everyone, before they go ahead and do it.
