Re: Covid "vaccine" is gene therapy
Please learn the differences between gene editing and abusing the cell's protein synthesis machinery - the latter is what the COVID vaccines do and there's no way for that to permanently change anything, since our cells have no way of turning RNA to DNA. In your code analogy, what actually happens with the vaccines is closer to someone getting creative with an API that can't affect global state than messing with the binary itself. It also affects only a small number of muscle cells - those get killed off quickly by the immune system (since they appear to be infected by a virus as far as that's concerned) and get replaced within a few days.
What the article discusses is something completely different, because it actually does alter the DNA in such a way that it gets copied along during cell division and they're doing it across most of the cell population responsible for a life-sustaining functionality. This is obviously far more risky - if it goes badly wrong, it's going to create a situation in which survival is unlikely. This is potentially a risk worth taking in a situation that's life-limiting anyway, but there's no way anything close to that level of risk is ever going to get regulatory approval for preventative purposes.
