This is a fantastic development in the fight against cancer and an encouraging result, of course the question becomes how do we insure, kill switches and all, that we’ve not designed a better “cancer.”

The current literature is bleak on the subject of controlling nature.

I agree with this. If they succeed in this, like I said, it could potentially save a lot of lives, especially those who have a family history with cancer. But I also agree with what you said, I hope that this modified virus won't kill "good cancer cells" or turn them into something way worse than existing types of cancers.
