But after five days, Sherif upped the game. He had the two groups compete for food. He limited their resources. It was a fist-swinging, curse-hurling, dust cloud of a mess. When a few punches landed, the adult researchers had to step in, adults with notebooks holding back furious Eagles and violent Rattlers.

Sherif concluded that scarcity was one of the main drivers of all human conflict. War, violence, invasion, and theft were all born of wanting a limited resource. The history of all humanity seems to support the hypothesis: We fight over water, cattle, arable land, ore deposits, oil, precious stones, and so on.

Big Think recently spoke with Oxford University philosopher Nick Bostrom about his new book, Deep Utopia. He’s got good news. Bostrom argues that the future will do away with the need for conflict over scarce resources. To him, the future is plentiful.

Frankly, I think 100 years is too far to look into the future because we will see dramatic new scientific areas emerge 20 years from now. My grandfather immigrated to Israel in 1946 from Holland to be a Technion student in civil engineering.

At that time, civil engineering and mechanical engineering were the most prestigious fields you could study. Back then, the disciplines of science that I work in, like computer science and electrical engineering, did not even exist as separate fields.

In comparison, today progress happens even more quickly. This rapid progress is especially apparent in disciplines like quantum technologies and AI.

But despite creating all these breakthrough technologies, physicists and philosophers who study quantum mechanics still haven’t come up with the answers to some big questions raised by the field’s founders. Given recent developments in quantum information science, researchers like me are using quantum information theory to explore new ways of thinking about these unanswered foundational questions. And one direction we’re looking into relates Albert Einstein’s relativity principle to the qubit.

Quantum computers

Quantum information science focuses on building quantum computers based on the quantum “bit” of information, or qubit. The qubit is historically grounded in the discoveries of physicists Max Planck and Einstein. They instigated the development of quantum mechanics in 1900 and 1905, respectively, when they discovered that light exists in discrete, or “quantum,” bundles of energy.
