Jack Dorsey says there is no moat, Musk and Saylor debate Bitcoin and AI protection

Block CEO Jack Dorsey posted "there is no moat" on X, referencing a leaked 2023 Google memo warning that open-source AI erodes the lead of closed labs. The phrase was linked to the launch of Dessa, a small voice AI model from Block that can run on a MacBook. MicroStrategy executive chairman Michael Saylor replied that Bitcoin itself is the moat, arguing it protects capital against inflation. Tesla CEO Elon Musk replied that Sparta never had a moat, relying on soldiers instead of walls.
