Tuttles All The Way Down – Digital Plumbing Upgrades Essential For Financial Services To Progress

Webinar Recording

"Turtles all the way down" is an expression of the problem of infinite regress. The saying alludes to the mythological idea of a World Turtle that supports the flat earth on its back. It suggests that this turtle rests on the back of an even larger turtle, which itself is part of a column of increasingly large world turtles that continues indefinitely (i.e., "turtles all the way down").

The exact origin of the phrase is uncertain. In the form "rocks all the way down", the saying appears as early as 1838. References to the saying's mythological antecedents, the World Turtle and its counterpart the World Elephant, were made by a number of authors in the 17th and 18th centuries."


However, "tuttle" is not a typo.

Archibald “Harry” Tuttle stars in the 1985 film, Brazil. You may remember the tagline of Brazil - “It's about flights of fantasy. And the nightmare of reality. Terrorist bombings. And late night shopping. True Love. And creative plumbing.” The hero, Sam Lowry, played by Jonathan Pryce, finds he has become an enemy of the state simply because he takes it into his own hands to correct an administrative error. In the film, Tuttle, played by Robert de Niro, is the rogue heating engineer out to solve people’s real plumbing problems “without filling out a 27b/6... Bloody paperwork”. He explains his motivation, “Why? I came into this game for the action, the excitement. Go anywhere, travel light, get in, get out, wherever there's trouble, a man alone".

Thus, Tuttle is a long-running conversation about interesting stuff with people who aren’t afraid to think about or work on radical new plumbing, such as new user interfaces, smart ledgers, artificial intelligence, financial innovation, scientific discovery, disaster relief, music, film, art, and where everything meets up in the Great Café that is London. Z/Yen was proud to host the peripatetic Tuttle Club for a few months back in 2016 - Z/Yen & Long Finance Bid Farewell To The Rogue Plumbers - The Tuttle Club.
