Vanderbilt University—one of the great research universities in the world—has chosen San Francisco as the home for a full-time academic campus. Beginning in 2027, Vanderbilt plans to bring students, faculty, and all the energy that comes with academic life into the heart of our city. If we want San Francisco to lead the future, we must compete for the institutions that shape it. Today shows what happens when we stay focused, work together, and aim high. San Francisco is on the rise. And we’re just getting started.

Have you been paying attention to the humanoid robots? We're close to having these in our homes. What many don't realize is that each robot (Atlas) uses 3.7kWh. which is 10x kWh/mile of an EV and 3x kWh of a Blackwell chip. We're gonna need more power. #AI #power #nuclear

Great post. Unfortunately, deepTech suffers in this new, narrowed attention on achieving breakeven. DeepTech requires true capital investment, and patience, as the market embraces the new new thing. Profitability comes next. It requires VCs with guts to withstand the valley.
The Grand Reset: VCs and LPs Are Starting To Internalize Reality The past few years in the VC space have been brutal. Darwin has returned from vacation and the frothy gold rush of the 2018-2021 startup ecosystem has vanished. The ZIRP environment caused valuations to soar and VCs threw money at any startup with a pulse. The money was put to work by Founders quickly, many of whom chased shiny objects and undisciplined growth because their bank accounts were flush with cash. But a harsh reality set in once we entered a new and higher interest rate economic cycle at the beginning of 2022: The vast majority of the high-flying ZIRP era startups are unlikely to deliver great financial outcomes for their investors and employees. Early in the correction cycle there was a lot of denial by Founders, VCs and LPs, but this denial has for the most part gone away. For many startups it’s clear that it will be challenging if not impossible to earn their way into their last valuation. For many investors it’s clear that they’re playing to recoup their money (i.e. – playing for pref) rather than playing for “fund returning outcomes”. And for many LPs, they realize that this is an industry wide phenomenon because every active fund manager played the game that was on the field. This has birthed a phenomenon that can be thought of as "The Grand Reset" where everyone in the ecosystem is seeking the cleanest path to a “do over”. Venture capitalists know that they have one or two funds that are going to underperform but are excited about their front book opportunities. So the “new deal” they’re making with LPs is that they’ll try to quickly recoup what they can and make the most of the back book in return for being more disciplined going forward. LPs understand that more investments than normal will fail and they know that absorbing those losses will lead to lower fund performance. LPs realize that the VC asset class is cyclical and great vintages can be created by great managers once the ecosystem flushes out the mistakes produced in an abundant and free flowing capital environment. The “new deal” they’re making with VCs is that they’ll forgive a bad vintage if the VCs will be honest with them about what the back book is “worth”, be more disciplined going forward and they’ll do everything they can to return some cash “soon”. And many Founders have realized that the ZIRP funding environment hurt their startups in multiple ways. First, their common equity is likely buried under a massive preference stack. Second, too much money caused them to hire too many people and invest in too many projects and undoing this has been challenging. Third, raising capital when a company has been in “shedding mode” rather than “growth mode” is difficult which puts re-booting growth at risk. And finally, the opportunity cost of trying to fix a broken business vs. starting a new one from scratch makes sticking around “expensive”. The net result of this “Grand Reset” is that there’s no longer incentive for anyone to maintain the illusion they can shepherd mediocre companies towards billion-dollar IPOs that aren’t going to happen. Instead, the focus has shifted towards "landing the plane" for the 90% of companies that aren’t ever going to achieve escape velocity. This generally means navigating an acquihire for struggling companies and helping “good but not great” portfolio companies find exits through acquisitions or mergers even if it means selling for a fraction of their inflated peak valuations. This shift can be brutal for Founders who envisioned a triumphant IPO. But for many, it's a wake-up call. The pressure to "grow at all costs" has receded, replaced by a need to focus on building sustainable businesses with real revenue models and clear paths to profitability. And "The Grand Reset" isn't just about selling off inflated companies. It's about resetting expectations on all fronts. VCs are re-evaluating their investment theses, focusing on strong unit economics and caring about capital efficiency. Founders are being forced to build businesses that can turn over cards in a disciplined way and survive without the crutch of endless VC funding. And LPs are seeking to re-up with Funds that have great pre-2018 track records and have a true competitive edge in today’s new normal environment. This new landscape has its downsides. The flow of easy money has dried up which makes it harder for promising early-stage startups to secure funding. But there are upsides as well. The emphasis on fundamentals could lead to the creation of a new generation of startups built on a foundation of sustainable growth, not just hype. The Grand Reset represents a significant course correction for the startup ecosystem. It's a painful process, but it could ultimately lead to a healthier and more sustainable future for both VCs and startups alike. As the dust settles, one thing is clear: The era of easy money is over. The startups that emerge from this reset will be the ones that can demonstrate real value and build strong businesses for the long term. (More on "landing the plane" in a thread next week).

Dear Crypto X, I am writing to you from the future. It's 2030 right now, and things are really hard It went downhill starting in 2025. The crypto bull happened. Stables exploded, and every app, game etc. started using ETH L2s for everything Overnight, web 3 became the web Then sh*t started hitting the fan. Chainspy started offering on-chain background checks, every social platform built on-chain search features, and then PScores launched. F*cking PScores! A PScore is your "perfection score." It algorithmically determines how "perfect" you are based on all your on-chain history PScores were marketed incredibly well and had great dev tools. They became the gold standard for verifying the "quality" of someone Because of my past mistakes, my PScore was low, and I could do nothing about it. I gambled too much in the past, bought weed, and have a script for OCD meds. I regret all of it. Crazy that I am talking about my OCD as something I regret.. When PScores exploded, I started getting blocked from things. I got kicked off almost every dating app. When I quit my job, I struggled to find another one And then PScore blocking became automatic. On the hot new social network, I could only connect with others with the same PScore range. The crazy stuff started happening when they began tying PScores in with facial recognition Security at every store now knows my PScore the moment I walk in. Police stop and frisk those of us with low PScores constantly and track us with the cameras on every city block There is talk about making PScores illegal, but they can do nothing. Pandora's box is open. There is no going back. Ethereum is immutable and public. I used to think those qualities were so powerful back in the day Without privacy, it's a cancer To everyone reading this letter, I hope you choose to do something about it. Please, I beg of you, don't give up your right to privacy so easily. Everyone will tell you that the purpose of blockchains is transparency. Tell them that's bullsh*t. The purpose of blockchains is to be the best truth machines in the world. That doesn't mean they have to become 1984-level surveillance tools! Fight for blockchains with default privacy. If not for my sake, then for yours Sincerely, John Smith

THE TECHNO-OPTIMIST MANIFESTO part 1 “You live in a deranged age — more deranged than usual, because despite great scientific and technological advances, man has not the faintest idea of who he is or what he is doing.” — Walker Percy “Our species is 300,000 years old. For the first 290,000 years, we were foragers, subsisting in a way that’s still observable among the Bushmen of the Kalahari and the Sentinelese of the Andaman Islands. Even after Homo Sapiens embraced agriculture, progress was painfully slow. A person born in Sumer in 4,000BC would find the resources, work, and technology available in England at the time of the Norman Conquest or in the Aztec Empire at the time of Columbus quite familiar. Then, beginning in the 18th Century, many people’s standard of living skyrocketed. What brought about this dramatic improvement, and why?” — Marian Tupy “There’s a way to do it better. Find it.” — Thomas Edison Lies We are being lied to. We are told that technology takes our jobs, reduces our wages, increases inequality, threatens our health, ruins the environment, degrades our society, corrupts our children, impairs our humanity, threatens our future, and is ever on the verge of ruining everything. We are told to be angry, bitter, and resentful about technology. We are told to be pessimistic. The myth of Prometheus – in various updated forms like Frankenstein, Oppenheimer, and Terminator – haunts our nightmares. We are told to denounce our birthright – our intelligence, our control over nature, our ability to build a better world. We are told to be miserable about the future.

This. Average age in the @BeePartners portfolio is 36 and climbing.
In a world of mostly 20-somethings being featured for accomplishments, It’s easy to forget that the average age of successful founders is actually 40 : - David Baszucki was 41 years old when he created Roblox - Eric Yuan founded Zoom at the age of 41 - Stan Lee created his first hit comic when he was 39 - Martha Stewart published her first cookbook at 41 - Sam Walton founded the first Walmart at 44 - Ray Kroc was 52 when he started transforming McDonalds You’re fine :)

So pleased to read that @calstrs selected such a strong group in @SapphirePrtnrs. Emerging Managers rejoice!
1/👑 Once upon a time, today's legendary venture funds were emerging managers… Which is why today I’m excited to share that @SapphirePrtnrs is launching a new program to invest in emerging venture managers with a sole LP, @CalSTRS, the world's largest educator-only pension fund! Why we are excited about this next chapter👇 🧵 As part of this new program, we are taking over the management of five existing CalSTRS “New and Next Generation Manager Funds,” representing $1.4B AUM.* Collectively, we have invested in 300 emerging managers. Our plan going forward is to invest ~$100M/year into emerging venture managers.🙌

NO GOOD DEED GOES UNPUNISHED: Elon Musk is the latest scapegoat for Ukraine’s failing counteroffensive. Appearing at the @allinsummit yesterday, @elonmusk addressed the controversy that erupted over the past week when an excerpt from @WalterIsaacson's new biography of him was released. The excerpt alleged that Elon turned off Starlink access to Crimea in order to prevent a Ukrainian drone attack on the Russian fleet based at Sevastopol last year. Elon has clarified (and Isaacson has acknowledged) that he didn’t turn off anything. Starlink had never been activated over Crimea because of U.S. sanctions on Russia. Ukrainian officials asked Elon in a late-night call to activate it for purposes of launching a highly provocative attack on the Russian fleet. Concerned such an attack would prompt an escalatory response — perhaps even a nuclear one — from the Russians, Elon refused the request. He told us at the All-In Summit that had the request come from the White House, he would have honored it. For this, Elon has been called “evil” by a high-level Ukrainian official, and treasonous by the usual warmongers here at home. The military blog 1945 questioned whether he was “fit to run SpaceX” and whether the company needed to be nationalized. MSNBC’s Rachel Maddow claimed Elon was “intervening to try to stop Ukraine from winning the war.” CNN’s Jake Tapper called Elon a “capricious billionaire” who “effectively sabotaged a military operation by Ukraine, a U.S. ally.” He demanded to know of his interview subject, Secretary of State Antony Blinken, if there should be “repercussions” for Elon’s actions. Tapper’s tirade echoed almost verbatim a cranky tweetstorm by neocon attack dog David Frum, who demanded Elon be investigated and stripped of his government contracts. According to Frum, Elon “confessed” to an “abuse of power” that “thwarted what might have been a decisive military operation to shorten the Russian war against Ukraine, (and) save who knows how many lives.” In Frum’s fantasy narrative, Russia would have responded to the drone attack by turning tail and leaving Ukraine, rather than massively escalating the war. A Baseless Frenzy of Attacks The frenzy of attacks on Elon illustrates how no good deed goes unpunished. He originally provided Starlink to the Ukrainians as an act of charity. There was never a contract and they weren’t formally a customer, just a recipient of free aid that Elon volunteered. Had he not done that, there would be no controversy today. At earlier points in the war, Ukrainian officials acknowledged that Starlink was not just an important communications channel – it was their only communications channel. It’s perhaps not an exaggeration to say that Starlink kept Ukraine in the war. Not only was this expensive for SpaceX, Elon explained at the Summit, it posed great risk to the entire Starlink network since the Russians would have a strong incentive to disrupt it, either by destroying satellites in space or by conducting a cyber-attack on SpaceX. As the creator and owner of this technology, Elon had the right to ensure that it be used for the purpose he intended — to help humanity rather than expand a war. Conversely the Ukrainian government had no right to conscript the resources of a private American company. Had he received a directive from President Biden, Elon would have complied as a patriotic American. Instead, he was asked by the Ukrainian government to enable a major act of war in the middle of the night and had reservations. Notably, Elon’s concerns were exactly the same ones that the Biden administration cited in refusing to provide ATACMS missiles last year — the risk that they would be used against Russian territory, precipitating World War III. Elon’s reservations were no more unreasonable than those expressed at the time by White House officials. The Purpose of Pushing This Narrative By volunteering Starlink at Ukraine’s moment of greatest need, it’s safe to say that Elon did more for the Ukrainian war effort than all the pro-war pundits, media personalities, and academics denouncing him now. To understand the ferocity of their response, therefore, we have to look at the larger context of what’s happening on the ground in this war. After months of grueling fighting, the reports from the battle fields have been “sobering”, the losses have been “staggering”, and the gains have to be “measured in meters rather than miles” (according to CNN). Suddenly there is recognition of massive Russian superiority in artillery and air assets (both of which should have been known before the counteroffensive). Despite the best efforts of Western media to spin the taking of some minor villages in the grey zone as a “piercing” of Russian lines, it’s become obvious that the counteroffensive has failed to achieve its originally touted objectives, like reaching the Sea of Azov and severing the land bridge to Crimea. In the wake of such disappointing, even disastrous results, the finger pointing and blame game have begun. American officials have criticized the Ukrainian military for abandoning the combined arms tactics they supposedly learned during their hurried NATO training and even for being too “casualty averse” in their willingness to accept losses. Ukrainian officials have chided American officials for unrealistic expectations and for failing to provide all the needed weapons. The Need for a Scapegoat While there has been no shortage of recriminations to go around, at the end of the day Washington and Kiev need each other. The Kiev regime would collapse without American support, and Biden’s re-election is imperiled if such a collapse happens before next November. A War Party divided against itself cannot stand. So a new culprit must be found to shift the blame for the foolish plan to run tanks into minefields and to throw human waves at prepared defenses with no air support or element of surprise. Most importantly, the scapegoat must be someone that neocons and the MSM can agree to hate and vilify. Elon Musk fits the bill nicely. Already flagged by president Biden as someone whose business dealings needed to be “looked at,” sued by Biden’s DOJ for hiring too many Americans at SpaceX, investigated by another government agency for allegedly building a glass house at Tesla, boycotted and accused of anti-semitism by the ADL for unbanning former president Trump on X.com, he is persona non grata to the MSM (who compete with X for attention and influence) and to DNC operatives who see his support for free speech as a threat. Finding convenient scapegoats when one of their foreign crusades goes spectacularly off the rails is nothing new for neocons. Their modus operandi is to push a dolchstoss (“stabbed in the back”) narrative that insists their grand plans for regime change would have succeeded but for some fifth column that undermined them, or a failure of nerve or competence on the part of leaders they exhorted into their quagmires. Elon Musk is not the reason Ukraine’s fortunes on the battlefield are flagging. He showed unusual generosity in donating Starlink and unusual judgment in floating a peace proposal last year that looks better by the day. If searching for culprits to blame for this war turning into a bloody quagmire, decision makers in Washington and Kiev and their enablers in the media – who confidently dismissed Elon’s pleas for negotiation in favor of launching this counteroffensive – should look in the mirror.
