Discuss & Social 🍷 How to not be replaced by AI?
Discuss & Social 🍷 How to not be replaced by AI?
**Discussion overview:** AI can write essays, generate art, and even build programs in seconds. As algorithms take over the office, many of us fear the pressure to become hyper-efficient machines just to survive. But is trying to beat AI at its own game a losing battle? Or is doubling down on our flawed, emotional human traits our best defense? Whether you're a creative, a young professional, or just trying to navigate a digital world, let's discuss what makes us irreplaceable... 1\. 🤖 **Beat the Machine:** Should we learn to work like AI, or focus on skills AI can never copy? 2\. 🎨 **The Creative Clone:** Can algorithms ever replicate true artistic vision and human empathy? 3\. 🥂 **Return on Investment:** Will AI force us to value real human connection over KPIs? *Join us for a relaxed group conversation where we explore real life, grey areas, and how our different cultures and backgrounds shape our views about key topics.* *Expect real talk, no judgment, and a chance to learn how others see it.* **\*Come for the discussion, stay for the friendships. Our weekly discussion series brings together thoughtful people for honest conversations on relationships, life, and society - with warm social vibes before and after.\*** **WHAT TO EXPECT:** * Good vibes only: we chat big topics in a chill, respectful way. No arguing - just open-minded exchange. * We warm up with casual socializing (come solo or with friends!) * The topic starts around 7:45/8pm, wraps around 9:30. * 🍕 There's pizza, drinks, milkshakes and snacks available at the bar (incl plant-based options) * And most people stay until late for drinks and mingling! **DISCUSSION FORMAT:** **\- Our group conversations are open and flexible\! There is a very soft guided flow to ensure we focus on the key questions\, and to ensure that everyone gets a balanced opportunity to speak\.** \- We rotate groups intentionally during the discussion so everyone gets to meet a wider mix of people and perspectives\. \- After the structured part\, you’re free to mix and mingle with anyone\. **Here's a typical discussion flow, but we may adjust this depending on the turnout:** \- Introductions and initial thoughts *(\~5 mins).* \- Group breakouts per question *(\~20 mins x 3).* \- Final round of opinions *(\~10 mins)*. \- Mix and mingle\, make new friends\, get drinks etc *(\~until late)* **Rules & etiquette:** 1\. Debate the topic\, not the participants \- no personal attacks please\. 2\. No phones\, no interrupting\, no bystanding\. 3\. Always follow the moderator/host instructions and guidelines\. **WHAT IS WORLD CITIZENS?** We're one of London's longest-running and largest communities. Since 2012 we run socials, cultural activities and stimulating discussions to foster meaningful exchange and learning among London's global professionals. They are inspired by MUN (Model United Nations) and salon discussions and offer a more relaxed and social evening version. **LOCATION DETAILS** What: Discussion session followed by social/networking When: Tuesday, 7:30pm until late. Where: Curzon Aldgate (bar area), 2 Canter Way, E1 8PS Closest stations: Aldgate East, Aldgate, Tower Hill/Gateway Cost: Pay for your own meals or drinks Hosts: We have a rotating team and the actual host of each event varies. Our regular members can also help you out with basic matters. *NOTE: like most guests, our volunteer hosts join after work and may arrive after the start time. If you are punctual or earlier than our hosts, we highly appreciate this! Please feel free to start socializing already and/or get something to eat or drink - that’s the point of our events anyway! Our regular members can also help you out with any basic matters.* **\*Our other weekly events\*** \- Friday evening socials every week \- Saturday afternoon cafe in Chelsea \- Canary Wharf socials every other Wednesday \- Outdoor fun \(hiking\, kayaking\, etc\) every weekend \- Dining\, cultural and travel activities on\-demand **JOIN OUR TEAM!** We're all volunteers, so if you enjoy organizing activities or events in your spare time, while meeting great people every week, send a message to our team account "TP"! **DISCLAIMER** We are a 100% volunteer-run team.

Conundrum Corner :: London - Your Dilemmas Discussed..
Conundrum Corner :: London - Your Dilemmas Discussed..
*a documentary film crew will be at this event - they will be discreet and omit anyone not wishing to be filmed* **✨ Welcome to Conundrum Corner at The Union Jack pub, Southwark! ✨** Step inside and join a gathering *of* open minds and kind hearts. Whether you bring a conundrum of your own that you are experiencing or simply your listening ear, you’ll find a welcoming space to share, reflect, and explore life’s tricky questions together. 🌿 **What to expect:** *You’re invited to share a conundrum, dilemma or question that you yourself are experiencing. - We’ll vote to choose a few intriguing ones to explore more deeply. *With a few extra details in hand, we’ll break into small groups for thoughtful discussion. - Then, we’ll come together as one big group to share insights, perspectives, and perhaps even some fresh solutions. The atmosphere is **analytical yet empathetic, thoughtful yet light-hearted**, and always accommodating. Whether your conundrum is personal, professional, or just a head-scratcher, we’re here to help unravel it together. 💸 There’s no set fee to attend, but we do ask for donations on the night to cover costs - which are warmly appreciated! 🍷 Please also support our lovely hosts, Jade and co., by buying yourself a drink at the bar (and food’s available if you fancy a bite). 💡 **What’s a conundrum, you ask?** A conundrum is any dilemma, crossroads, or confusion in your life—big or small. It could be a **"chicken and egg"** situation, a **"catch-22"**, or a **"have your cake and eat it"** kind of puzzle. Sometimes, life just throws us complex, messy questions—and that’s what we’re here to navigate together. Once our deep discussions wind down, we’ll slip into **pub mode**—a chance to relax, connect, and continue chatting with newfound friends. **🛡️ Code of Conduct - *please note*** Conundrum Corner is committed to providing a safe and respectful environment for all attendees. Any abuse, harassment, or inappropriate behaviour towards other attendees, whether during the event or in any contact related to the event afterwards, will result in permanent removal from the Meetup group and exclusion from future events. Come along for an evening of intriguing conversations, fresh perspectives, and a touch of serendipity. Looking forward to seeing you there! Helena x

Drunken Philosophy: Are you really who you think you are? What is the "self"?
Drunken Philosophy: Are you really who you think you are? What is the "self"?
I have been studying the question of "self" online with Prof. Ellie Anderson and so I thought a prompt on the "self" might be interesting. Full confession: I had Claude create this prompt and I like it, so here goes: Imagine a thought experiment that merges two classic puzzles: > You undergo a procedure, performed neuron by neuron, in which every biological component of your brain is replaced with a functionally identical synthetic substitute. At each step, your behavior, memories, and personality remain unchanged. When the last neuron is swapped, is the consciousness experiencing the world still you? And — more pressingly — was there ever a continuous "you" to begin with? ### Questions to Wrestle With * If consciousness is purely physical, does the *gradual* nature of the replacement matter, or is it equivalent to being destroyed and rebuilt? * Could there be a "self" without continuity of experience — even moment to moment, while you sleep? On a more practical level, consider the simpler case first: **hemispherectomy** patients — people who have had an entire cerebral hemisphere surgically removed — often retain a strong sense of personal identity and continuity. This suggests "you" are not rigidly tied to specific physical material. But does that vindicate the synthetic neuron case, or merely show that identity is more *flexible* than we thought — not that it can survive *complete* substrate replacement? I used Claude so I could get this out today and let everyone have some time to consider it. Hope to see you at the Oracle. Sorry about the location change two weeks ago. That's what I get for trusting local weather predictions!
