For me, there are four fields in science and technology which will be the foundation of our future.
Energy and climate; biology and medicine; information technology; space.
There’s more to life, sure, but those four fields are what I think are worth my time.
Space is the long-term, existential problem, perhaps a lower priority, within our grasp but not yet our reach. With biology and medicine, and information technology, we can change the world more immediately.
It is energy and climate that is both immediate and existential.
That is why the US withdrawal from the Paris Agreement on climate change is so extreme an event, so great a threat. It exceeds even the historic excess of Donald Trump’s short presidency, and requires a firm and clear response from the world: No, this is not OK.
