“I’m an optimist because I know what technology can accomplish and I know what people can accomplish.” – Bill Gates

Despite my scientific training and engineering background (or perhaps because of them) when talking about the climate emergency, I’ve generally been wary about going down the route of tech-optimism, of believing that there’s a technological solution to the problem just around the corner. There are three broad reasons for this. The first is that risk that the tech fails and leaves us in a worse place than we currently are. Continuing to emit carbon until the day that a tech-priest grants us the blessing of effective carbon capture only works if the blessing actually arrives. If it doesn’t, then we’re left with a larger problem and even less time to fix it. And a strategy like “Net Zero” that fixes part of the problem (like EV cars fixing carbon emissions) but doesn’t address the rest of the problem (overall air quality) isn’t even a solution.
