I think that it's an interesting breakthrough (15 years in the making) and potential achievements could be huge.... using these bacteria to, as they (The JCVI) put it, "suck carbon out of the atmosphere, clean polluted water, or sacrifice their own microscopic lives to become energy-rich components of biofuels"....
There is a concern that the risks of this project could be enormous to human life but the JCVI team reiterate that "no applications of this work will or should be attempted in humans." How true that is....i don't know. The project is moving forward, whether some of us like it or not; we just have to hope that it's closely monitored and the project moves at a pace where nothing horrible happens so we have a good understanding of the implications.....
