**Explore AI over dinner at a Michelin-listed London restaurant. Tools, opportunities and real conversation.** Each Meet2Click Curated Conversation dinner centres around a carefully chosen topic or shared interest, designed to spark thoughtful conversation and meaningful connection. **Curious about how AI is changing our lives — and want to explore it in a relaxed dinner setting?** Artificial Intelligence is evolving rapidly. New tools, ideas, and breakthroughs are reshaping how we work, create, and think. Instead of abstract debate, this evening is about sharing what we’re discovering in real life. Two days before the dinner, guests will receive a short, accessible overview of interesting AI tools — simply to spark ideas. At the table, we’ll explore: • What AI tools have you tried recently? • What discovery or breakthrough impressed you most? • Where do you see the greatest opportunities emerging? No technical background required. **Launch Season Benefit** During our initial Meet2Click dinners, guests will enjoy **up to 50% off food** at the restaurant. This introductory benefit is available for a limited launch period. Food and drinks are paid individually, directly with the restaurant. **Details** Location: restaurant Bala Baya, Arch 25, Old Union Yard Arches 229, Union Street, London SE1 Date: 8 April 2026, 19.00h **Ticket price:** £15 per person *(includes your seat and contribution to the evening — food and drinks ordered and paid individually at the restaurant)* Seats are intentionally limited to encourage meaningful conversation and genuine connection. Just an open, relaxed exchange of ideas over dinner.

On Wednesday 8th of April, public rallies and other events are taking place around the world in support of greater funding for research into longer healthy lifespans. [The Fund Longevity website](https://fundlongevity.org/en/why/) makes the case as follows: ***Aging Is a Problem***: Aging kills around 110,000 people every day. It is the primary risk factor behind nearly all major non-infectious diseases, including cancer, heart disease, and dementia. Beyond statistics, aging causes decades of frailty, pain, and loss of independence. It is the greatest source of human suffering that is being accepted as "normal". ***This Is Personal***: Everyone you love will age, suffer, and die because of it. So will you. If we had the ability to prevent this, choosing not to would be deeply unethical. If we can stop aging, we should. ***Stopping Aging Is Possible***: Aging is not a mystery or a force of nature. It is a biological process — and biological processes can be studied, modified, and treated. Over the past decades, scientists have identified many of the core mechanisms that drive aging at the cellular and molecular level. While our understanding is incomplete, it is already sufficient to begin developing real therapies. ***What Do We Mean by "Stopping Aging"?*** We mean treating aging as a medical condition. The goal is to restore and maintain youthful biological function — roughly equivalent to being in your twenties — for as long as you choose. This would prevent or reverse age-related diseases instead of treating them one by one. ***Is This Really Realistic?*** Yes. Thousands of scientists have publicly stated that aging is a solvable problem in the [Dublin Longevity Declaration](https://dublinlongevitydeclaration.org/). Research already shows that aging can be slowed, paused, or reversed in laboratory organisms. Some animals exhibit negligible aging or extreme longevity. Nature has already demonstrated that aging is avoidable — humans simply haven't applied these solutions to ourselves yet. ***Is It Difficult?*** Extremely. Reversing aging in humans will likely be more difficult than landing on the Moon. It will require entirely new biotechnologies and breakthroughs that don't exist yet. We will need to remove senescent cells, repair or replace damaged tissues, and solve many other problems we don't fully understand. This is one of the most difficult challenges humanity has ever faced, but just because it is difficult does not mean it is impossible. Many scientists agree that there are no fundamental laws of physics that prohibits stopping aging. Nature has done it in several animals already, like the hydra. ***What's Missing?*** Scale. Today, fewer than a thousand people worldwide are seriously working on solving aging — researchers, biotech founders, and advocates combined. That number needs to grow by at least 1000×. There is no major government agency dedicated to ending aging. Funding is fragmented. Regulation is outdated. Public urgency is nearly nonexistent. This will not change on its own. ***Why We Act***: Aging is the largest cause of death and suffering on Earth. Solving it requires a society-wide effort — scientific, political, and cultural. That's why we organize. That's why we demonstrate. That's why we demand action. Join us — and help make aging optional for humans and animals.\* == London Futurists gathering on 8th April == The arguments for greater funding for longevity science are strong - but at least a dozen arguments are often raised in opposition to such funding. In our gathering in *Ye Olde Cock Tavern* in Fleet Street, we'll take the opportunity to review these arguments - debating their merits, taking them apart brick by brick, and exploring what really lies behind these arguments. *Anyone who wishes to make a short presentation on this topic during this gathering should contact the organisers in advance.* == Schedule == 5:30pm: The room is available, for early get-togethers 6pm-6:45pm: Food is served; informal conversations 6:45pm-8:30pm: A number of interactive conversations, interspersed with opportunities to visit the bar 8:30pm: Informal networking == RSVP please == Registrations are capped at 40 people. *First-time attendees are welcome.* There's no charge to register or attend, but the pub will expect everyone to order at least one drink, and a reasonable number of attendees to [order some food to eat](https://www.greeneking.co.uk/pubs/greater-london/ye-olde-cock-tavern/menu?type=main+menu). Please order your food on your arrival, so that all plates can be set aside by 6:45pm to allow everyone to concentrate on the main discussion! == More about the venue == Ye Olde Cock Tavern, 22 Fleet Street, Holborn, London, EC4Y 1AA See [https://www.greeneking.co.uk/pubs/greater-london/ye-olde-cock-tavern](https://www.greeneking.co.uk/pubs/greater-london/ye-olde-cock-tavern) We'll be meeting in the room at the top of the stairs, though drinks should be ordered from the bar on the ground floor. \*\* Note that this is an in-person meeting, and there will be no remote access, sorry \*\*

Elixir London Meetup; February 2026 edition. All are welcome. **Session 1: Anton Borisov - Distilling Kafka's Binary Protocol into Elixir** We'll trace a produce request to show what any Kafka client has to get right. In the BEAM ecosystem, erlkaf wraps librdkafka, brod implements the protocol in Erlang, and [kafka_ex](https://hex.pm/packages/kafka_ex) goes pure Elixir. Kafka_ex's approach is to generate serializers at compile time from Kafka's own schema definitions: plain structs, pattern matching, structural boilerplate isolated from the logic you actually think about. That design is what let us jump two major versions ahead and adapt to significant protocol changes. Let's dig into the idea, the code, and the tradeoffs. **Session 2: Evadne Wu** **\- JavaScript Execution Strategies in Elixir\-based Agent Frameworks** We'll look at integration points between elixir agents (in the AI fashion) and JavaScript execution, and all the foot guns involved. *The event is kindly sponsored by* [Fresha](https://www.fresha.com). **Time** Doors open at 18, start at 18.30. **Venue** Fresha The Bower, 207-211, Old St, Tower, London EC1V 9NR **Refreshments** Food and drinks will be provisioned on the day. **IMPORTANT**: **If you wish to take photos and post online during the event, please notify organisers first, so that attendees can opt-out from being in photos.**

This is a smaller version of our usual StitchUp meetings, hosted in my studio in Bloomsbury. Made for a smaller group in a more quiet setting. Tea and water, biscuits will be provided. **Welcome to StitchUp** – a welcoming social group that embraces individuals of all skill levels, providing a shared space for crafting in a social setting. **Bring your current project**, whether it's knitting, quilting, embroidery, or any other textile craft. Work on your project or piece while having a chat with us. Some people knit, some people mend or just join the conversations. If you are starting new, I’m sure we can give you tips, but generally this is not a class or workshop and you will have to bring your own materials.
