I have some opinions about “Premium Rush” I’ve been wanting to get off my chest.

AI agents can prototype apps… But shipping real software takes hours of testing, debugging, and refactoring. Agent 3 is 10× more autonomous — it keeps going where others get stuck. The “Full Self-Driving” moment of software.

In December of 2023, we shared how a16z will become more active in supporting pro-technology candidates across the country. Aligned with that strategy, today we announced our contribution to the Leading the Future PAC (@LeadingFutureAI), which will support leaders who understand the promise of AI and the importance of getting policy right. AI isn’t hype or science fiction—it’s already here. This technology can drive the next wave of American growth, create new jobs, and unlock productivity across every sector of the American economy. But make no mistake: this is also a race with China. If we don’t have the right policies, we risk ceding the future of AI—and with it, America’s economic strength and national security. Policymakers in Washington and our state capitals are weighing thousands of proposals right now that could make it impossible to build. The only way to counter entrenched interests and outdated thinking is to make sure builders have a voice at the table. That is exactly what LTF will do—through coalition building, education, and supporting bipartisan, pro-technology candidates who understand what’s at stake. @a16z is proud to stand with this effort to ensure America leads in AI—and that Little Tech innovators have the clarity and support they need to keep building the future here at home. prnewswire.com/news-releases/…

Margit built @a16z with @bhorowitz and me from the start to what we are today — we can’t even imagine how we could have done it without her — her genius, judgment, and wisdom have been invaluable. ❤️
Margit Wennmachers@wennmachers

Time for a Margit update! Here is the news: I’m “graduating” from operating partner to partner emeritus @a16z. First, let me back up. It seems that I do things in decade and a half increments. I got to the US in 1991 (October 19 is like a sort of birthday. Ask any immigrant and they will know their US birthday!). There was a tech recession at the time. Also, no American resume. Nor academic credentials. But this is America! And it came through for me. I spent a few years trying to get a job. I got a temp job at a tech PR firm. Then I got my first real break. A huge thank you to @simonecoxe and @maureenblanc for giving me my first real job and a shot at an actual career. That was a job as Account Executive at Blanc & Otus. I worked there for 4+ years. Then the talented @carynm650 and I started The Outcast Agency, which turned out to be the very best tech comms firm in the world. We built Outcast into the most sought after firm for tech franchises for over a decade and a half. We sold it to Nextfifteen (thank you, @timdyson . So that house was built; it’s still around and has amazing clients. @bhorowitz and @pmarca came calling. Before they ever raised money. These guys were ballsy. It was the height of the financial crisis, there was zero liquidity. Ben and Marc wanted to raise $300m. Just the two of them. When probed on this, Marc just said, “Let’s assume success, shall we?” Despite the risk…. It was a chance to build the top brand in venture capital. Period. Mind you, back then no VC firm was doing any marketing at all. It was seen as almost unseemly! I love building so I took a chance. The founders made me - I think - the first VC firm CMO. Now every firm has one of those, and that’s a good thing. Over the last 15 fabulous years, we’ve done so many things: - We marketed ahead of any result. We had to. So we marketed people and their ideas. - We invented going direct, creating a powerful content operation that allows us to communicate on our terms. - We produced events where people tried to crash multiple times and had to be escorted out by security. - Literally so many firsts and big things, there are too many to list them all. Now we actually have results! And we’re still the most exciting brand. a16z is full of talented people giving their best, full of amazing portfolio companies, and a very large and powerful network that everyone in our orbit can plug into. I can’t possibly thank every single person in the firm here, so I will keep it to the founders for being committed to building the top brand, and to @garcegarce of course. She was my first hire - she also took a chance on me and our entire project. Finally, a heartfelt thanks to the indefatigable @Mili10 , who has made my life easier and more productive for a decade. My sincerest thanks. Many more of you deserve a thank you, I’ll ping you directly. What’s ahead? I will be an active advisor for the next 6 months. We all want to make sure the change is smooth, in particular for the folks in our network who have a long-standing relationship. After that, I will not be gone and dead, haha. While I’ll take a nice break, I’ll also be looking for what to build next. My number won’t change. So feel free to reach out if you need anything. The house is built. I will forever bleed a16z. Here’s to more building!

#### 2. "US birth rate has been below replacement since ~1971, except for a split second echo of the baby boom." - **Data Validation**: The U.S. TFR dipped to 1.84 in 1971 (CDC) and has rarely exceeded 2.0 since, with a notable exception around 2007-2009 (reaching 2.12 in 2007) due to delayed childbearing from the baby boom generation. Macrotrends.net reports a 2024 TFR of 12.01 (crude birth rate per 1,000 population, up 12.23% from 2023’s 10.70), but this metric differs from TFR, which remains sub-replacement. Musk’s “split second echo” likely refers to this brief 2000s blip, emphasizing the persistent decline. - **Sociological Factors**: This trend correlates with urbanization, higher education costs, and shifting gender roles—factors predating AI. For instance, the 1970s saw women’s labor force participation rise from 43% to 51% (U.S. Bureau of Labor Statistics), reducing time for child-rearing. Musk uses this to argue that AI is a symptom, not the cause, of broader societal changes. - **Counterpoint**: ℜ𝔞𝔢’s reply (1949201919148474729) argues that AI’s hyper-stimuli (e.g., virtual companions) could accelerate this by replacing human interaction, a view supported by some neuroeconomic studies (e.g., ScienceDirect, 2014) linking dopamine to reward-seeking behavior that might prioritize virtual over real-world reproduction. #### 3. "AI will increase birth rates in order to maximize the future light cone of neurotransmitter tonnage." - **Core Claim**: This is where Musk pivots to optimism, asserting AI’s potential to reverse the trend. The phrase is dense with meaning, so let’s dissect it. - **"AI will increase birth rates"**: Musk suggests AI could incentivize or facilitate reproduction. This might involve AI-driven matchmaking (e.g., optimizing partner compatibility), assisted reproductive technologies (ART) like IVF enhanced by machine learning (as noted in npj Digital Medicine, 2024), or even social engineering via AI platforms to promote family values. The web result on ART highlights how AI could personalize fertility treatments, potentially boosting live birth rates for the 1-in-6 infertile couples globally. - **"Future light cone"**: A term from physics (relativity), the light cone represents all possible events an observer can influence or be influenced by, given the speed of light. In a futurist context, Musk often uses it metaphorically to describe humanity’s long-term impact on the universe. Here, it implies AI’s role in shaping a prosperous, expansive human future, possibly through population growth. - **"Neurotransmitter tonnage"**: This is a quirky, Muskian way to quantify happiness or well-being, with neurotransmitters (e.g., dopamine, serotonin) as proxies. Neuroeconomics research (ScienceDirect, 2014) shows dopamine encodes reward prediction errors, driving behaviors like reproduction when rewards are high. “Tonnage” suggests a massive scale—maximizing collective human satisfaction over time. Musk might envision AI optimizing societal structures (e.g., education, healthcare) to make parenting rewarding, thus boosting birth rates. - **Speculative Mechanism**: This could involve AI creating immersive, family-friendly virtual environments (e.g., an evolved Vine) that encourage social bonding, or even bioengineering (e.g., Neuralink enhancing reproductive instincts). It aligns with xAI’s 2025 mission to accelerate human scientific discovery, potentially including demographic solutions. - **Great Filter Connection**: The thread’s “Great Filter” hypothesis (ScienceDirect, 2024) posits AI superintelligence could end civilizations by outpacing human control. Musk counters this, suggesting AI might instead be a tool to overcome the filter—low birth rates and extinction—by enhancing survival instincts. His multiplanetary vision (e.g., Mars colonization) supports this, where AI ensures a robust human population.
