**This talk has completely sold out in advance and no additional tickets will be sold at the door. A repeat of the talk at Penn Social in DC on Monday, May 18 still has tickets available.** [Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“How AI Alters Thinking,”** on dealing with artificial intelligence’s capacity to change and undermine our thought processes, with Eli Alshanetsky, assistant professor of philosophy at Temple University, principal investigator at its Cognitive Integrity Lab, and author of an upcoming book on AI and freedom of thought. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-how-ai-alters](https://events.ticketleap.com/tickets/profsandpints/nv-how-ai-alters) .] Doctors who give bad advice can be sued for malpractice. Teachers belong to a profession with set standards. When artificial intelligence guides you, however, that guidance comes with a disclaimer: Use at your own risk. Every day millions of people take that risk, and usually AI seems genuinely helpful. But even if AI gives us good answers, might its use over time do bad things to how we think? Explore the relationship between AI and our own minds with Eli Alshanetsky, whose Cognitive Integrity Lab studies how artificial intelligence changes how we think, learn, and build trust. Author of *Articulating a Thought* and the upcoming book F*reedom of Thought in the Age of AI*, he’s on the cutting edge of efforts to answer AI-related questions such as: How can we tell when work is truly our own? How can technology support rather than replace authorship and reflection? What does trust mean when AI mediates our relationships with others and with our own thoughts? To set up his discussion of potential consequences of AI, he’ll describe how social media’s impact on society serves as a preview. Social media didn’t just give people what they wanted to click on, it actually changed what they regarded as click-worthy. It broke attention spans and fueled radicalization across millions of very different people. It left us with people who doom-scroll for hours, who can’t focus, who don’t know what to trust anymore. If you’d shown people this version of themselves ten years ago, would they have chosen it? Artificial intelligence is making a similar deal with us, but the stakes are higher. It isn’t chasing clicks. It’s optimized for giving you the most satisfying response to whatever is on your mind right now. The risk over time isn’t just that you’ll get lazy. More profoundly, even when you think hard, your sense of what counts as good thinking—as well as what sounds like you—will shift to match what AI has been feeding you. We’ll consider what kind of person this produces and whether this is someone we want to be or want children to become. Professor Alshanetsky will lay out a practical framework, which he calls “the interaction layer,” for using AI without letting it replace the thinking it’s supposed to support. He’ll also talk about what AI-related concerns should be the focus of parents and educators. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Feeling down? Sometimes depressed? Can't focus? Negativity & stress? Recent losses? Creativity in career and personal life hindered by mental blocks? Sometimes we never fully recover from traumatic experiences. Whether it was yesterday, last week or a year ago, traumatic experiences - a loss of a loved one, losing a job, a breakup - can leave you scarred. You talk about it and feel a little better, but it never goes away. After you hang up the phone, it's still there; the sadness, the cloud, the over-thinking, the worry, the guilt. You try to focus, but you're blocked. You try to look forward into new experiences, new relationships but a cloud is hanging over you, casting a shadow on what you once considered a bright, cheerful future. What happened to your courage? Your strength of character? You're 'why not' attitude? Whoever said 'time heals' must have had a special time machine, because after weeks, months, years, you're wondering - when exactly does that kick in? Sometimes it seems like drinking or drugs are the way to go. But they wear off, and now the problem is still there with added side effects from the drugs. At this free local Meetup event we will talk about: * What causes grief, anxiety and depression to become chronic. * Is it possible to regain your joy and happiness even after traumatic experiences? * How to break away from negativity and focus on the future * What are the steps to take to get control of your mind and your emotions? Learn about a safe, gentle, do-it-yourself counseling that can be done in the comfort of your own home. Let's explore safe, effective solutions for healing from traumatic experiences. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This group is sponsored by the Dianetics & Scientology Life Improvement Center.
