If you started vibecoding something with Fable, but then the gubment banned it, and you go down a model, is that a “Vibing for Algernon” scenario where you sense you are witnessing and experiencing IQ plummeting ?

( TEMPO ) Gaining control 🎯 The soft-landing shot is one of the most important shots in the short game. It's a mid-flighted shot that lands softly onto the green with control, allowing you to access tighter pins and get it close on firmer greens. T...

This is the easiest way to show you the simplified MATCHUP between body rotation & shaft pitch. The steeper you are, the more you have to tilt in order to get the club back in position. If you try rotating instead, you’ll get way too steep on it. The shallower you are, the more you need to rotate in order to get the club back into position. If you try tilting, you’ll get stuck way underneath and will suffer from all sorts of low point and contact issues. This is a big reason why being shallower is specifically better for golfers who want to rotate more through the shot. Enjoy! 🤙

I just got back from SF and I FEEL INSPIRED. I spent 5 days with frontier AI model teams, AI startup founders, and 3 billionaires. My takeaways: 1. I had lunch with 3 billionaires. All of them are buying SaaS companies and rebuilding them agent-first. They were deeply inspired by Bending Spoons and Ryan Cohen's eBay deal. Buy the company, cut the headcount, rebuild the tech, add agents, add features, make more valuable experience, raise prices. 2. The frontier model companies are hungry for usage data from the field. They can see API calls and token counts. They can't see the actual workflows. If you're deep in a niche using these models in ways the model companies haven't seen, that understanding is incredibly valuable. Usage intelligence is the new alpha. 3. Consumer AI is massively underbuilt. Every billboard in SF is either B2B inference infrastructure or vertical agent companies. The entire city is optimized for enterprise. Meanwhile you have companies like Cal AI doing $50M ARR in 18 months as a consumer app. I met with a cool few teams doing consumer AI (@paulscherer / @ekuyda) 4. MCP came up in literally every conversation. The companies exposing their product as MCP endpoints are getting pulled into deals they never pitched for. The ones that aren't are becoming invisible to agents. This is the new SEO. If agents can't find you, you don't exist. Building products for agents is the new zeitgeist in general. 5. Not uncommon for hot seed rounds to be $25-50 million valuations. I saw a Series A at $450 million 6. If I had a dollar every time someone mentioned "forward-deployed engineer" this trip I could have funded a seed round. It's the hottest role in SF right now. The person who sits between the agent and the customer, making sure everything actually works. 7. The mood around open source shifted. A year ago it felt like open source was chasing the frontier models. Now founders are telling me Gemma and DeepSeek are good enough for 80% of what they need at a fraction of the cost. The "which model do you use" conversation is being replaced by "which model for which task." Model loyalty kinda feels dead. 8. Voice agents came up more than I expected. Multiple founders told me voice is the interface for the next billion users. The billion people who will never type a prompt will absolutely talk to one. 9. The Obsidian community in SF is weirdly intense. Multiple founders showed me their vaults unprompted. Like showing someone your home gym. It's a flex now. The quality of your knowledge base (second brain?) is becoming a status symbol among builders. 10. Maybe it was just the people I met but the age of the founders is shifting. I met more founders over 40 this trip than any trip before and more founders under age 21 than ever before. Founders getting older and younger at the same time. 11. I spoke to a lot of fast-growing startups, VCs and frontier models who are hiring content creators right now. 12. The restaurant scene in SF is actually better than it's been in years. Founders are going out more. Alcohol is out, not surprisingly. 13. SF doesn't feel like the only place anymore. We all have access to the same frontier models. We all read the same X feed. A founder in NYC or Lagos is calling the same APIs as a founder in SoMa. So in the past it felt like SF was always lightyears ahead, doesn't feel that way anymore. It's okay not to live in SF and have BIG DREAMS. 14. The coworking spaces in SF are half empty but the coffee shops are packed. People want to be around people. I had a few startup ideas here.... 15. Walking around the Mission I noticed something: the street-level businesses, the taquerias, the barbershops, the laundromats, none of them use any AI at all. 16. I heard the phrase "agent debt" for the first time. Like technical debt but for agents. When you hack together an agent workflow fast and never clean it up, the system prompts conflict, the memory gets polluted, the tools overlap. 6 months later the agent is doing weird things and nobody knows why lol. 17. Met a few people who carry two phones now. One for personal. One that's basically an agent terminal running Telegram or iMessage connections to their agent fleet. It's always amazing to get that dose of inspiration in SF. I FEEL INSPIRED. But I'm so happy to be back home, locked in and building. We're 12-18 months into a shift that will take 15 years to play out. The urgency in every conversation was real. What an incredible time to be building.

If you haven't tried a meeting AI assistant yet, here's your sign (and a free month). Paid partnership with Ping Assistant. I'm calling Ping a Productivity Advisory Assistant. Yes, a brand new term. After testing it out in my own firm, the most interesting part of Ping wasn’t even the notetaking. It was seeing how AI can help organize information, surface ideas, reduce admin friction, help firms operate more effectively, and make more money. Here's my in depth video going over all the features in Ping! Check out the link in the comments to get a FREE MONTH of Ping.

Today, we’re announcing Viktor’s $75M Series A, led by @Accel . @viktor__com was supposed to be a small experiment. It became the AI coworker 10x'ing real businesses. $15M in annualized revenue run rate. In 10 weeks. – Small companies saving millions of dollars – Sourcing hundreds of thousands in new revenue in their first 30 days – Whole teams getting half their week back – Companies running 40% leaner without cutting output Viktor is not another AI tool. It’s the first true AI employee. The vision that has been with us since 2023 when we started the company has finally been shipped. Back then, it was just the two of us, with a very small but dedicated team, iterating for years. Failing multiple times. Showing products that users didn't even want to test! But we never gave up. Our decisions were often wrong. Certainly more often than not! We kept trying. Now we’ve shipped something people love. Worth every sleepless night. Every sacrifice. The best employees don’t need to be told what to do. Neither does Viktor. Grateful to @Accel, our team, our earliest users, and everyone who believed this category could be bigger than chat.
Community note
Viktor operates a creator program paying users up to $2000 per promotional post on X that includes real product screenshots, with no requirement to disclose the payment. getviktor.com/creators

I’ve been using Viktor over the last three days as an “AI employee” to do work I’ve been putting off for years (listing out every Open Forum video clip since 2015..about 60 hours of footage) and I highly recommend you try it out inside of Slack. No cost, no credit card required. app.viktor.com/signin?ref=bS…

There's no good Tax AI for people with quick questions. People always have follow-up q's on QSBS, 1244, SAFEs, startup equity. So until I build it - 𝐦𝐲 𝐃𝐌𝐬 are the best Tax LLM (quick questions only!). But just like AI, I only have the context you give me!

Cameron Young’s force and 3D capture at TPI in January. One of the most unique transitions in golf. One of the best tee to green on the PGA TOUR.

The Billionaire Tax is actually an Everyone Tax. The Billionaire Tax is a new tax proposal written by four professors who don't believe in the American dream. Some of them aren’t even American…go figure. Despite its name, it applies to every California resident who currently has assets or ever will. The creators named it the Billionaire Tax so you would get into a froth andwouldn't look closely at what it actually does to you. On page twenty-six, it explains how the government can convert to an Everyone Tax without voter approval. They can also adjust the tax to be a yearly tax, not just one time…again, without your approval. Here's how the tax would work: As a voter, you're being asked to approve a tax that would require you to: 1. list all your assets and the value of each, then submit them to the California Franchise Tax Board. 2. authorize the tax board to appraise your assets and confirm the value of each. 3. pay a penalty of up to forty percent of your tax bill if the board determines your reported value was too low in their opinion. 4. allow the tax board to subpoena your financial records from every one of your financial institutions for auditing. This Everyone Tax runs 34 pages of shifty language describing how the government plans to take your assets. Read the fine print and decide for yourself. If this were truly a billionaire tax, it would be 3 pages. It’s 34 pages so that it can create the mechanisms to steal from all of you.

One good way to get to know fresh faces on tour is to watch the entire masters coverage of holes 15 and 16 amen corner from start to finish multiple times…. Ask me how I know.

This is so good. Watching Scottie Scheffler on the range is gold. Best player in the world. On pace to be one of the best ever. Yet his practice obsession? The GRIP. The most basic fundamental in golf. He uses a standard grip trainer constantly.
