21 in 21: Rainey Reitman on Transaction Denied and Financial Censorship

Rainey Reitman joins 21 in 21 for a conversation on financial censorship, free speech, and her new book, Transaction Denied: Big Finance’s Power to Punish Speech. Rainey co-founded Freedom of the Press Foundation and serves on the board as president. She also spent 11 years at the Electronic Frontier Foundation, first as Activism Director and later as Chief Program Officer. Drawing on years of work in civil liberties advocacy, Rainey explains how lawful speech can still lead to frozen accounts, denied payments, and exclusion from the financial system. She also shares how these issues connect to journalism, whistleblowers, privacy, and Bitcoin’s promise, and limits, as a censorship-resistant tool.

21 in 21: Michael Saylor on Bitcoin, AI, and Advice for Builders

Michael Saylor joined Haley Berkoe on 21 in 21 for a rapid-fire conversation on bitcoin, AI, and what’s coming next. He shares what’s top of mind for 2026, why he sees this year as a major turning point, and how he thinks bitcoin could evolve as digital capital beneath new layers of credit and currency. Then, Saylor gets into how AI will radically transform civilization, and how that shift could make bitcoin even more important in a world where autonomous agents need to transact constantly with digital capital. He points to Strategy’s use of AI in creating digital credit products like Stretch (STRC), and shares the kinds of bitcoin products he hopes to see, from deeper integration into everyday technology to applications powered by bitcoin. Saylor emphasizes that we’re entering one of the most fertile periods ever for building, and encourages builders and young people to spend a lot of time learning AI tools and continually pushing themselves to create something new and useful. There are also a few fun detours into MIT prank stories and the AI-generated X profile images he’s become known for.
