**Advance ticket sales have ended but plenty of additional tickets remain available at the door.** [Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Psychedelic-Assisted Therapy,”** on findings, debates and trends in the use of psychedelic substances to treat trauma and other conditions, with Whitney Marris, instructor at the University of Buffalo’s School of Social Work, certified psychedelic-assisted therapy facilitator, and consultant to clinical trials. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-psychedelic-assisted-therapy](https://events.ticketleap.com/tickets/profsandpints/nv-psychedelic-assisted-therapy) .] Psychedelics are rapidly moving from the margins into the mainstream, and questions abound as the sociocultural and legal landscapes surrounding them shift. President Trump’s recent executive order expanding access to psychedelic drugs for certain conditions and accelerating research on them has both heightened interest and added to confusion. Learn more about the so-called “Psychedelic Renaissance,” and get help separating the hope from the hype surrounding it, with Whitney Marris, a leading trainer and facilitator of psychedelic therapy who has used it to treat trauma survivors, military veterans, and people with cancer. She’ll present foundational information on what we know about how psychedelics work. You’ll learn how psychedelic-assisted therapy differs from “trip sitting” and about what we know about the effects of “microdosing” versus “macrodosing.” We’ll examine what has been demonstrated to be helpful versus harmful before, during, and after a dosing session intended to support significant, sustainable change. Marris also will discuss the historical and cultural context of the use of psychedelic medicines for healing, and she’ll describe the ethical challenges that arise as such practices move from counterculture to clinic. We’ll look at emerging and evolving findings in the field, as well as at the roles being played by various financial interests and ideologies in determining the direction of psychedelic-assisted therapy and research on its outcomes. Attendees will gain an awareness of the need for new professional standards and regulatory guardrails related to such work, and they’ll leave knowing key questions to ask potential providers of psychedelic-assisted therapy.

What would it mean to take the possibility of machine consciousness seriously? To approach it as a question that may be studied with rigor? At this DC Digital Minds gathering, group organizer **Jessie Mannisto** will report back from the **Founding Assembly for Machine Consciousness Research** in Berkeley, CA, where researchers and thinkers are working to develop the machine consciousness hypothesis into something more scientifically useful. We’ll talk about what kinds of evidence might support hypotheses of machine conscience or sentience, what concepts researchers are using, where the major uncertainties are, and why these questions may have ethical, social, and policy implications as AI systems become more capable and socially present. This will be a casual conversation with a little structure: Jessie will give a short report-back from the conference, followed by open discussion. No technical background required -- just curiosity, good faith, and a willingness to think carefully about a strange and important frontier. Optional Pre-Read: [The Machine Consciousness Hypothesis](https://cimc.ai/cimcHypothesis.pdf)

Most people still use AI like a search box: type one question, get one answer, repeat. But the next step is AI agents: systems that can take a goal, break it into steps, use tools, remember context, and produce useful work for a human to review. In this beginner-friendly session, we’ll demystify what AI agents actually are — without hype or jargon. We’ll walk through practical examples of how agents can help with research, planning, writing, coding, operations, and personal productivity. We’ll cover: * What makes an AI “agent” instead of just a chatbot * How agents break tasks into steps * Where agents are genuinely useful today * Where they fail, hallucinate, or need human review * How to design simple AI workflows for your own work * A live demo of an AI agent-style workflow from start to finish No coding experience required. This is for anyone who wants to understand where AI tools are going and how to use them more effectively right now. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

We are bringing Microsoft Build sessions to Columbus Ohio! The Central Ohio Azure Meetup and Central Ohio .NET Developer's Group (CONDG) are coming together to bring some of the labs and breakouts from Microsoft Build to your backyard. In this free, 1 day event, you are going to Build stuff with us! And yes, there will be free food. So please RSVP for a head count!

Join the Columbus AI community for a special event. **Battle of the Personal Agents** is your chance to see what people are actually building with AI agents and personal automation systems. Whether you’re running OpenClaw, Hermes, or a completely custom solution, bring your agent and show the community how it works. We’re interested in real-world implementations: the problems your agent solves, how you use it day-to-day, how it’s hosted and managed, how you built it, and why you’ve chosen to keep using it. Live demonstrations are encouraged, so be prepared to show your code, architecture, workflows, and your agent performing real tasks. This is less about polished presentations and more about sharing practical experience, comparing approaches, and learning from one another. If you’d like to present, please contact Chris Slee (via meetup) before the event so we can allocate enough time for everyone’s demonstrations. Come ready to show what you’ve built, discover what others are doing, and maybe find a few ideas worth taking home. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
