TEDxOtemachi 2023 gives people who care about sustainability and progress an opportunity to spark discussion on the future of humanity, and share those ideas with the global community.

The theme of this year is“Perseverance”. TEDxOtemachi 2023 features innovators from across disciplines who will speak to a variety of issues regarding our long-term future - the trajectories of not only organized human life but also other sentient beings on Earth. We will explore diverse ideas, such as exciting technological innovations, new ways of organizing human systems, strategies to hedge against existential risks, or how to extend consciousness and live a flourishing life in harmony with nature. Faced with unforeseeable changes that the future brings, opportunities and crisis alike, it’s high time we ask: “The future is vast. The future can be exciting. Future people matter. Is there anything we could do to – reliably and significantly - improve the long-term future?”

If remaining on Earth, humanity could continue for 600 to 800 million years, as long as the Earth is habitable. This means that there could be as many as 21 million future generations, and even more if we move our habitat to another planet, possibly controlling the energy of the entire galaxy in a few hundred million years. A future beyond our imagination awaits us.

Where are we heading?

As technology evolves, there are risks that threaten the existence of the entire human race, or permanently destroy humanity’s long-term potential (e.g. nuclear weapons, AI, pandemic, etc.) Sustainability is hardly possible without hedging these risks.

As the world changes and grows more complex, it’s important that we discover the means to three fundamental transformations: Secure Life, Expand Consciousness, and Elevate Well-being.

“The blush of health on a convalescent’s cheek. The twinkling of the eye in a moment of wit. The smile of a loving thought… Utopia is the hope that the scattered fragments of good that we come across from time to time in our lives can be put together, one day, to reveal the shape of a new kind of life. The kind of life that yours should have been.”

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.
