>"Let me make it very clear: fusion is, if you simply look at the carbon dioxide goals we have, fusion would be too late to bring those carbon dioxide emissions down at the rate that we need. If renewables do the job, fusion could become part of a network of dispatchable power generation units. However, if renewables don’t do the job, fusion will be too late to prevent serious damage. In that scenario, we would find ourselves in a bad situation for a period of time that extends beyond when the first fusion reactors come on line."

This quote is so telling on the limits of technology. So many people think of fusion as a technological miracle that can save the world. Here we have a man telling the world that we're fucked if we just sit on our asses waiting for this miracle.
