A new technology, called gene drives, has the power to spread any genetic instructions you wish across an entire animal or plant species in the wild. It might let us restore ecosystems ravaged by invasive species, or help species adapt to climate change. And, it might save millions of children from dying of malaria. But could altering nature in this way, and on this scale, have unintended consequences? And, when it comes reshaping ecosystems, who needs to say yes?

Artificial intelligence is letting us make predictive algorithms that translate languages and spot diseases as well or better than humans. But these systems are also being used to make decisions about hiring and criminal sentencing. Do computers trained on vast datasets of human experience learn human biases, like sexism and racism? Is it possible to create an algorithm that is fair for everyone? And should you have the right to know when these algorithms are being used and how they work?

Fully autonomous lethal weapons—robots that can select and engage targets without human intervention—are fast becoming possible. They might minimize casualties and protect civilians in times of war. But is it morally wrong to put a computer in charge of life or death decisions? Could system errors lead to flash wars? But, as war gets faster and more complex, is it even feasible to keep humans in the loop?

Could altering the Earth’s atmosphere to reflect back some of the sun’s rays be a solution to climate change? It would likely decrease global temperatures, but it might lead to climate wars. Humanity might become “addicted” to it for survival. And ultimately, would this technology only distract us from tackling the real problem of carbon emissions?

It’s getting easy to create convincing—but false—videos through artificial intelligence. These “deepfakes” can have interesting applications in art and education, but they can also cause great harm—from ruining the reputation of an ex-partner to provoking international conflicts or swinging elections. When seeing is not believing, who can we trust, and can democracy and truth survive?

Malcolm Gladwell joins host Dr. Eric Lander for a conversation about science, society, and how the decisions we make today will impact generations to come. At a moment when science is becoming more important than ever for meeting the challenges ahead, can we solve the growing tensions between society and science?
