Learning as the Goal: Astro Teller on Why Failure Is the Engine of Innovation

"Think of the last really hard thing that you and a team did," Astro Teller says. "Now imagine you lose all of the hardware, all of the software, anything except what's in your and your team's heads. How long, once you've succeeded, would it take for you to go back and rebuild the solution?" Most people answer somewhere between 5 and 20 percent of the original time. For moonshots, Teller says, it's closer to 5 percent. "What are we going to call that other 90 percent of the work? It's learning."

Teller is captain of moonshots at X, Alphabet's moonshot factory, and in this conversation with Stanford lecturer Matt Abrahams, he lays out a framework for how to pursue audacious ideas without being crushed by the near-certainty of failure. The core insight is deceptively simple: if you want to do things that have a one-in-a-hundred chance of working, you cannot tie your sense of worth to getting a yes. You must instead build systems that reward learning itself.

Show Notes

“You learn nothing when you’re right.” 

Effective communication isn’t about having all the answers. As Astro Teller knows, it’s about finding, and sometimes fumbling, your way through the questions. As Captain of Moonshots at X, Alphabet’s Moonshot Factory, Teller embraces what he calls “a learning journey,” where being wrong isn’t the end, but an opportunity to discover something new. In this episode of Think Fast, Talk Smart, Teller and Matt Abrahams discuss how embracing uncertainty drives innovation, why leaders should reward learning over outcomes, and why sometimes being wrong is the best way to learn.

Takeaways:

  • Being wrong is where learning happens. Treating failure as useful information rather than something to avoid helps you stay curious, test assumptions, and discover better paths forward. 
  • Reward the habits that lead to innovation, not just the outcomes. Focusing on curiosity, humility, and experimentation creates space for people to take meaningful risks and pursue ideas that may not work the first time. 


Activity:

  • Find the failure faster. Choose one idea or project you’re confident about and identify the assumption most likely to prove you wrong. Design one small test that could challenge that assumption, then treat whatever you learn as progress.
