You'll hear Will O'Brien explain why autonomous underwater robots could unlock a new era of ocean exploration and security, Turner Caldwell discuss rebuilding America's critical minerals supply chain and modernizing mining, and Doug Bernauer share why portable nuclear microreactors could transform how we generate power. Together, these conversations offer a look at the technologies—and the founders—working to rebuild the industrial foundations of the United States.   Resources: Follow Will O'Brien on X: https://x.com/Willob Follow Turner Caldwell on X: https://x.com/tbc415 Follow Doug Bernauer on X: https://x.com/dougbernauer Follow Erin Price-Wright on X: https://x.com/espricewright Follow Ryan McEntush on X: https://x.com/rmcentush Follow Theo Jaffee on X: https://x.com/theojaffee Stay Updated:Find a16z on YouTube: YouTubeFind a16z on XFind a16z on LinkedInListen to the a16z Show on SpotifyListen to the a16z Show on Apple PodcastsFollow our host: https://twitter.com/eriktorenberg Please note that the content here is for informational purposes only; should NOT be taken as legal, business, tax, or investment advice or be used to evaluate any investment or security; and is not directed at any investors or potential investors in any a16z fund. a16z and its affiliates may maintain investments in the companies discussed.
