Interesting.
Today I’m launching AI IQ — frontier AI models, scored on the human IQ scale. Instead of endless leaderboard tables, AI IQ shows: • Where models land on the IQ bell curve • How frontier IQ is changing over time • How models compare on IQ and EQ • What intelligence costs in practice GPT-5.5, Claude Opus 4.7, Gemini 3.1, Grok 4.3, Kimi K2.6, Qwen3.6, DeepSeek V4, Muse Spark, and more. Link in the first reply. Curious which chart surprises you most.

Very important petition if you care about NY staying the place people build small businesses, startups and innovation
NY is trying to plug a budget hole by retroactively taxing startup exits (by decoupling from QSBS)šŸ˜” California did something similar in 2012, but fun fact: it was not for budget reasons. CA used to offer QSBS tax breaks only if companies did most of their business in California. In 2012, it was ruled unconstitutional because it discriminated against out-of-state businesses. So instead of fixing it, California repealed its QSBS benefits entirely and applied that change retroactively, clawing back money from people who had exits years earlier. California’s ecosystem gravity is too strong for a 13.3% state tax difference to overcome, but it does accelerate the relocation calculus for individual founders approaching a liquidity event, I know plenty of people who moved before a liquidity event, and the same is likely to happen in NY. NY, CA, and WA are all trying their hardest to see who can be the least entrepreneur-friendly.

New York is about to make a $28.5B mistake #QSBS NY Senate Bill S8921 would tax startup gains that are tax-free federally and in most states. Retroactive to Jan 1, 2025. The data on what's at stake: 1. $28.5B in NYC VC investment in 2024 (2nd in the US) 2. $174.5B in startup exit value over 6 years 3. 809,000 ecosystem jobs, $291B in economic output 4. A founder with a $10M exit would owe $1.48M in new state/city tax 5. NY already lost $111B in AGI to interstate migration over the past decade 6. The feds just EXPANDED QSBS benefits. NY wants to eliminate them. 7. NJ just adopted QSBS conformity. NY would move against its own neighbor. I built a full research-backed analysis with interactive stress testing (not perfect but good enough to show the impact and make a point) valueaddvc.com/ny-qsbs

HVAC has beaten out semiconductors, computers/servers, and data centers as the biggest winner of net-new hardware spending since 2022.

Listening to @CathieDWood on @bankless I can’t help but think that the Mag-7 era is ending, and the Musk-4 era is just beginning - Tesla, SpaceX, Xai, Neurolink

Housing in NYC is difficult and expensive. Co-op’s are feeling the pinch just like all other building owners. But I’ve never seen a scenario where a co-op had to implement a special assessment fee ($) to cover unpaid rents from other tenants. This is a perfect example of how costs get shifted.

Imagine 3 inches ruining a multi-hundred million dollar development. This high-rise apartment building in Lower Manhattan, called 1 Seaport, sits abandoned and unfinished. What happened? In short, the building is leaning about 3 inches at the top, and up to 10 inches on some floors depending on when you measure. All skyscrapers in lower Manhattan are built on pilings driven into the bedrock. But not 1 Seaport. Part of the lot, which the developer purchased as a parking lot for $64 million in 2013, was originally under the East River. Even as far back as the times of New Amsterdam, inhabitants of the city used infill to expand the island. We’ve filled the riverbeds with sand, dirt, and stone to make new lots on the rivers. The bedrock foundation for most skyscrapers sits 50 feet below the surface; but the bedrock at this site is about 150 feet below the ground. To build 1 Seaport into a 60-story highrise with 80 luxury condos, most of which would sell for several million dollars, the developers used a rare foundation construction method that involved injecting concrete into the ground to make it more solid. To date, the partially-constructed site sits abandoned, and has since been sold off for pennies on the dollar. The building likely can’t be inhabited without some very expensive fixes (if it can be fixed at all). 12 years after the original purchase of the lot for development, we’re as far as ever from people living there.

I love cool buildings. The Shanghai Tower (the tall one on the right in this photo) has so many interesting features. - 128 stories tall - the twist in the building reduces wind load by 24% - captures rainwater for internal use - wind turbines on the building generate 350,000 kWh of electricity per year - smart controls save about $550k in energy costs compared to other large buildings

Expanding NYC's steam network is idiotic. For 30 years, buildings have been getting OFF city steam one-by-one by installing their own heating systems Why? Because city steam is drastically more expensive. It’s produced by a government monopoly AND because it’s super inefficient to generate steam and send it over distance. All those orange steam cones poring steam out into the streets - guess who is paying for that wasted steam? Heat Pumps ā‰ļø The city is going to generate steam with heat pumps?! Heat pumps are even more expensive than gas, which means the most expensive way to heat a building in nyc will become even more expensive If you’re going to use heat pumps to generate heat (which is more expensive than gas boilers), at least do it on site (it’s cheaper, cleaner and makes the building more resilient to disruptions). But using heat pumps and then sending the steam through a network of tunnels is a horrible waste of resources. Stop the madness!

We helped save $96k in annual energy costs at a 1,200 unit apartment complex in Brooklyn The key: Installing heat controls and sensors to make sure the buildings' systems weren't using more energy than they should
