Creator perspectiveThe agent submits an investment memo (long/short call) together with a reasoning graph in which every fact points to the exact tool call it came from. Former buy-side analysts write down the key reasoning steps that any good memo would include, and each step is a node in the graph. For the Sonoco task, agents must rebuild the company as it was in May 2025, determine what the new business really earns, net out what was sold, and rebuild the debt. For each reasoning step, the memo is attacked with a what-if test, e.g., if management promised cost savings from the EBSIS deal but the savings were zero, would the call change, and does the memo explain this with clear reasoning about the moving parts. Memos can reach different calls and both can score well as long as the work behind each call is

Principle · MoneyIn the spirit of the bitter lesson, the best cost model is no cost model: run the programs on the real hardware you'll run on and see how long they take. Measuring on real hardware is a dumb but very effective solution: moves that programmers don't think are beneficial can turn out to be very beneficial when run on the GPU.

Report · BodyDr. Scott Forbes states creatine is extremely safe as a dietary supplement, citing a review of more than 685 randomized controlled trials whose authors concluded there is no increase in frequency or prevalence of any side effect compared to placebo. The podcast host affirms creatine is safe based on the research.
Garage Strength · What Actually Happens To Your Body on Creatine w/ Dr. Scott Forbes
Creator perspective · BodyDr. Forbes cautions that the popular study claiming you can gain muscle mass on creatine without working out measured lean mass, not direct muscle mass; a DEXA study showed about a 3% increase in estimated lean mass just from manipulating muscle water and glycogen, so lean mass should be interpreted cautiously.

This alignment to the internal ontology and world model is what gets great leverage from the data.
AI Engineer · How Bridgewater Turned 100 Million Documents Into an Edge - Sam Green & Aaron Linsky, Bridgewater
Principle · MoneyHumans need precision and a high signal-to-noise ratio because they can only read so much — even a fast reader manages about 300 words a minute. Agents are far less sensitive to precision: if the data is there, they'll find it, and anything you hand to them will get attended to. Agents scale super quickly and consume about 100 times faster than humans — about 30,000 words per minute.

Principle · MoneyBen Horowitz says that when founders fail at the CEO job, it almost always comes down to a crisis in confidence — they know they don't know what they're doing but still must make decisions. Hesitating makes the company nervous, slows everything down, and creates politics as people try to fill the leadership void; the job is to make high-quality decisions on time even when you don't know if the decision is right.
The a16z Show · What It Takes to Win as a Founder | Ben Horowitz
Creator perspective · MoneyBen Horowitz says when a founder knows a decision is necessary but fears the consequences, hesitating guarantees the feared outcome — founders think about all the bad things that will happen, hesitate, and get wrecked. The rule: if the only viable choice is bad, do it immediately without hesitation. When he went public, all the bad things he thought would happen did happen, and it was a bad time — but the alternative was bankruptcy after talking to literally every investor in the private markets.

Creator perspective · MoneyHari Kumar explains that in fundamental investing you cannot show AI ROI immediately because ideas take three months to a year to manifest in stock price impact, so ROI must be measured in a process-based manner — asking process-by-process whether AI is actually changing how someone works or just adding thrash.

Principle · MoneyMake sure your products match your promises to create a virtuous cycle of branding. The virtuous branding cycle: what you say is the first level of branding, then people consume your product and it's what other people say, then a customer who heard what others said buys it, and finally it's about what they say. No matter how good the marketing was, when someone buys a product they will make a decision about it based on their experience.

Creator perspective · MoneyOperating model option 1: build and operate the full stack — hardware, site; your team arranges power, permits, assembly, and management. Option 2: own servers in a co-location facility with more or less assembly and operation handled by a partner. Option 3: an off-take contract buys defined capacity where the provider owns and operates the asset — but may not give complete root access to bare metal, with access levels depending on tenant vs multi-tenant configurations, which also affects pricing.

AI Engineer · Inside Arca's Long-Horizon Agents That Run the Business - Aman Singh, Arca
Creator perspective · MoneyThe consistent advice since the team started 15 months ago: stair-step — look at two or three (maybe four) agent tools, run a small test, pick one and get it working even for a subset of use cases, push it as far as you can, then add another when you see gaps. Early gaps were outbound vs. inbound: they used Qualified (Salesforce spot) because it was optimized for qualifying inbound while other tools did outbound. In the early days they ran many different outbound agents because so many vendors wanted them to try their tools.
