This month's prompt concerns the idea of the โ€œwarrior philosopherโ€ (seemed appropriate in these times)--that is someone whose understanding of violence, power, and justice is forged through direct experience of war. We are looking at Major General Smedley D. Butler, a highly decorated U.S. Marine raised in a Quaker (pacifist) tradition who later became a prominent critic of American militarism (there is a wonderful biography of Gen. Butler called "Gangsters of Capitalism") Butler's argument in *War Is a Racket* (1935): that many U.S. interventions were driven less by national defense than by corporate and financial interests, with Butler portraying himself as an enforcer for business and Wall Street. We can consider the moral ambiguity of his insider critiqueโ€”whether complicity strengthens or undermines credibility and also consider some of the concrete reforms he proposed (e.g., โ€œconscriptโ€ capital before soldiers, restrict the military to coastal defense, and have only those who fight decide on war). Butlerโ€™s life arc clearly changed from pacifist upbringing to warrior to antiwar crusaderโ€”and asks whether true understanding of peace requires firsthand knowledge of war, and what that implies about the cost of suffering. So do we need to suffer to understand suffering? Do we have to experience war to appreciate peace? As one more question: in the movie "A Few Good Men" Jack Nicholson's character says that "you have the luxury of not knowing what I know" so do most of us go through life oblivious to real violence and suffering? See you at Drunken Philosophy!

AI is changing how art is made. But when does it stop being your work and start being the machineโ€™s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation?

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD
