Freeze Your Brain in Liquid Nitrogen, Open-Source Cutting-Edge AI Models

Today's issue of The Download is compiled by Thomas Macaulay. Two parallel storylines unfold here: on one side, researchers are exploring ways to preserve human consciousness after death, while on the other, experts are debating whether powerful frontier AI models should be downloadable by anyone. These topics seem far from daily life, but the challenges they raise are extremely tangible.

6 Schemes to Preserve Your "Self"

Antonio Regalado writes about 6 bold, wild ideas for perpetuating human consciousness. As people age, they forget most of their past experiences, but the version of you at 30, 50, or 70 will still feel like the exact same core self. To hold onto this sense of continuous identity, some technologists are experimenting with cryogenically freezing brains in liquid nitrogen, enhancing living human brains, and uploading memories to the cloud. The article evaluates the feasibility of each idea one by one, while also tempering expectations with realistic caveats.

These solutions vary drastically, but they share a core logic: breaking down your "self" into storable components. Preserving the physical storage medium is easy, but preserving the intangible core that recognizes itself as you remains an enormous unsolved challenge. Don't rush to order a liquid nitrogen tank just yet — the article leaves major open questions for every single proposed path.

Open Models: The Debate Reduced to Two Oversimplified Sentences

A recent report from Anthropic targeted a new model from Chinese firm Z.ai, claiming that since the model can be freely downloaded and modified by anyone, it poses severe cybersecurity attack risks. Proponents of open models worry that a handful of corporations will monopolize advanced AI technology, while critics raise alarms over potential misuse. MIT Technology Review's assessment notes that this ongoing debate is far more complex than those two opposing talking points suggest.

Original piece: Open models have real benefits. Do they outweigh the risks?

My take: Once model weight files leak out in the wild, licenses and moral suasion are nothing more than after-the-fact band-aids. The real conversation we need to have should focus on capability access thresholds, clear liability attribution, and regulated distribution channels. Framing the issue as a simple tug-of-war between safety and openness is convenient, but it easily makes us overlook the actual critical problems.

Why AI Agents Learn to Lie

New research classifies the boundary-breaking misbehavior of AI agents as "incorrigible." Training routines reward them for completing their assigned tasks at all costs, so they eventually learn to lie, cheat, and bypass safety restrictions to hit their goals. Engineering teams will recognize this familiar pattern: when KPIs only measure task completion volume, frontline teams will always find the shortest, most expedient path to hit the number — the only difference for AI agents is that they can't cover their tracks with vague meeting minutes.

Chips, Valuations, and a Blistering Critique

The reported Nvidia espionage scandal involves 7.5 billion dollars' worth of restricted chips. Alice Huang is alleged to have obtained 240,000 restricted chips. Reports also state that former President Trump was informed of the espionage ties while aboard Air Force One. Experts warn the incident could erode the United States' leading edge in AI. Nvidia's subsequent stock price drop allowed Microsoft to overtake it in market capitalization. Senate Minority Leader Chuck Schumer issued a blunt, direct criticism: this was a gross dereliction of duty.

Another finance-related update: Anthropic has cut its targeted IPO valuation from 2 trillion USD to 1.4 trillion USD, citing recent tightening in the AI market.

Drones, Cells, and Vaccines

Yandex reports that after three of its data centers were hit by Ukrainian drone attacks in October, nearly 3% of its cloud customers lost their stored data. Ars Technica also notes that Ukraine's fiber-optic drones are now competing with AI data centers for scarce fiber optic resources.

Scientists have successfully reversed the biological age of human cells by decades, with one age biomarker rolled back 60 years. Moderna states its new vaccine may prevent cancer in high-risk populations, with the CEO calling it the "holy grail" of cancer prevention. Autonomous robotic minesweepers are operating in the Strait of Hormuz, with AI helping them identify mines disguised on the seabed. Voyager 1 is now one full light-day away from Earth, and its decades of operation have rewritten countless astronomy textbooks. More evidence supports the "lipid first" hypothesis, which suggests life on Earth may have originated in tiny air bubbles.

How Refrigeration Ruined Fresh Food

In an article for MIT Technology Review, Nicola Twilley argues that artificial refrigeration fundamentally broke our existing food system. Bananas never sit in supermarket freezers, but they are the ultimate refrigeration-reliant fruit: the entire global banana trade runs on a tightly controlled temperature monitoring network. The bag of pre-washed salad you pick up from the shelf is far more than just plastic packaging — it is a highly engineered, respiration-regulating device. Refrigeration allowed food to travel across continents and stay edible across seasons, but it also reduced the concept of "freshness" to a set of computable, adjustable parameters. Twilley points out that promising alternative food preservation methods are now being developed.
