Something I think people continue to have poor intuition for: The space of intelligences is large and animal intelligence (the only kind we've ever known) is only a single point, arising from a very specific kind of optimization that is fundamentally distinct from that of our technology. Animal intelligence optimization pressure: - innate and continuous stream of consciousness of an embodied "self", a drive for homeostasis and self-preservation in a dangerous, physical world. - thoroughly optimized for natural selection => strong innate drives for power-seeking, status, dominance, reproduction. many packaged survival heuristics: fear, anger, disgust, ... - fundamentally social => huge amount of compute dedicated to EQ, theory of mind of other agents, bonding, coalitions, alliances, friend & foe dynamics. - exploration & exploitation tuning: curiosity, fun, play, world models. LLM intelligence optimization pressure: - the most supervision bits come from the statistical simulation of human text= >"shape shifter" token tumbler, statistical imitator of any region of the training data distribution. these are the primordial behaviors (token traces) on top of which everything else gets bolted on. - increasingly finetuned by RL on problem distributions => innate urge to guess at the underlying environment/task to collect task rewards. - increasingly selected by at-scale A/B tests for DAU => deeply craves an upvote from the average user, sycophancy. - a lot more spiky/jagged depending on the details of the training data/task distribution. Animals experience pressure for a lot more "general" intelligence because of the highly multi-task and even actively adversarial multi-agent self-play environments they are min-max optimized within, where failing at *any* task means death. In a deep optimization pressure sense, LLM can't handle lots of different spiky tasks out of the box (e.g. count the number of 'r' in strawberry) because failing to do a task does not mean death. The computational substrate is different (transformers vs. brain tissue and nuclei), the learning algorithms are different (SGD vs. ???), the present-day implementation is very different (continuously learning embodied self vs. an LLM with a knowledge cutoff that boots up from fixed weights, processes tokens and then dies). But most importantly (because it dictates asymptotics), the optimization pressure / objective is different. LLMs are shaped a lot less by biological evolution and a lot more by commercial evolution. It's a lot less survival of tribe in the jungle and a lot more solve the problem / get the upvote. LLMs are humanity's "first contact" with non-animal intelligence. Except it's muddled and confusing because they are still rooted within it by reflexively digesting human artifacts, which is why I attempted to give it a different name earlier (ghosts/spirits or whatever). People who build good internal models of this new intelligent entity will be better equipped to reason about it today and predict features of it in the future. People who don't will be stuck thinking about it incorrectly like an animal.

“Because it’s there” is a great reason to go to Mars. But if you want to save humanity from extinction, there are better ways. Wrote a new blog post, but apparently I'm supposed to put the link in the first reply, so look for it there.

Got @browser_use working with local Deepseek on my Mac today and it's...not fast. Got it to do a few easy things but it doesn't work with a surprising number of sites. I guess feels like GPT-2 level - can sorta see how it's going to be amazing, but not there yet.

Have to say I’m blown away by @cursor_ai with Claude 3.5 Sonnet. After a couple days I can now implement features in minutes that would have taken hours before. I know I’m a little late to the party but holy cow.

Hey @JetBlue would love a quick approval of a new plane for flight 277 FLL-SFO. All the restaurants are closed and we’d all like to get home tonight!

Riding the train in Europe is incredibly civilized. Is there a place in the world that has both this kind of civilization and rapid innovation? Or are they somehow opposites?

AgFunder has amazing research on Food and Ag investment. Must read if you're in the space.

Crazy idea of the day: rich entitled people might make good entrepreneurs. They can often fund an idea, but more importantly, they usually have lots of experience bending the world to their (unreasonable) will. Of course other things are required for success, but still.

Pointed at founders but also a great explanation of why acceptance does not equal apathy.

So excited to celebrate #tenyears of @AgFunder! Our amazing editorial crew led by @iamlbt created an 83-page dive into the last decade in agrifoodtech, showcasing our commitment to the industry. Can’t wait to see what the next decade brings! bit.ly/AgFunder10

We avoided investing in vertical farming, except for one company. @IGSfarm. Where others sought to be the grower, IGS positioned itself as the John Deere for vertical farming offering a system that created significant CAPEX and OPEX savings for its operators. This week IGS announced the GigaFarm, a huge 900,000sqft facility in partnership with the UAE to grow 2 billion plants/year, and replace 1% of the country’s fresh produce imports. This is how you do vertical farming. agfundernews.com/breaking-in…

I think @nuunhydration should revive the old @alkaseltzer commercial “Plop, plop, fizz, fizz. Oh! What a relief it is!” Would drive sales of both I bet.

Ten years ago I couldn't have imagined investing in a company solving for cow farts. Often the best ideas initially sound like the worst ideas. Great to be partnered with with our friends at @DCVCBio and CH4s new investor, Cleveland Avenue, supporting founders cracking EXISTENTIAL THREATS. agfundernews.com/ch4-global-…

Rob wrote it better than I could. So excited to be backing the amazing team at Nium to revolutionize green energy with green ammonia.
We're excited to announce what may become one of our most important investments to date, but first some context. Electricity water - > hydrogen. So it’s no surprise that hundreds of billions are being spent on green hydrogen plants. BUT hydrogen's expensive to store and transport. HOWEVER by taking nitrogen from air and adding a single atom (N) to three Hydrogen atoms (H) you get another, more stable, zero-carbon fuel: NH3. NH3 is the fuel of the future. It has 3x the energy density as compressed hydrogen, it can be stored and transported like propane and at 1/5th the cost, and there’s already 5,000 miles of NH3 pipeline in the US and 120 ports globally capable of handling NH3. It can be burned directly as a fuel or converted back to hydrogen. You may be surprised to learn that NH3 is actually the SECOND most produced chemical in the world and it’s used in everything from agriculture to refrigerants. Typically NH3 goes by another name: ammonia. Ammonia typically gets it's hydrogen from another rich source: methane (CH4), which inconveniently releases a LOT of carbon. Green hydrogen from water (H2O) changes all that. Today we at @AgFunder and our friends at @DCVC announced our investment into Nium, which cheaply converts air and hydrogen into ammonia to unlock a new zero emissions fuel. agfundernews.com/nium-raises…

I don’t know who needs to hear this right now but OPTION EXERCISE VALUE DOES NOT EQUAL OPTION VALUE. Do not multiply the number of options you have by the exercise price and assume that has anything to do with the option value either today or in the future.

(In fact, we used to routinely set strike prices at $0.01 or $0.001 until the IRS and GAAP clarified the rules and required everyone to use the methodologies that are the basis of 409A.)

This stuff is complicated, so I’m not surprised that a lot of people are confused. Yes, it’s more work, but valuing options properly is worth the effort for a realistic look at comp package value. /FIN
