Brian Armstrong on Bitcoin, Anthropic Drops Fable 5 & Mythos 5, NewLimit's $435M Age-Reversal | 264

Bitcoin: Institutional Flip, Price Outlook, and Quantum Risk

• City Bank projects Bitcoin at $189,000 by end of 2026; Brian Armstrong sees $100-200k plausible by year-end.
• Bitcoin down due to AI absorbing risk capital, stablecoin hype (Genius Act), and inflation trade losing steam.
• Bitcoin is digital gold but only ~30% of capital treats it as such; 70% still risk-asset like tech stocks.
• Quantum risk: BIP 360 proposes post-quantum cryptography; block size increase contentious; Satoshi's 5-10% coins may be frozen if not upgraded.
• Coinbase established Quantum Advisory Council with Dan Boneh, Scott Aaronson, Justin Drake, Yehuda Lindell.
• Three options for unupgraded coins: freeze (option A), allow seizure as bounty (B), or hybrid with appeal mechanism.
• Bitcoin mining competes with AI for energy and chips; Ethereum moved to proof-of-stake, 99.9% more efficient.
• Poly market predicts Bitcoin at $84,000 by end of 2026; daily trading volume 5% vs gold's 0.5%.

AI Agent Economy: Coinbase as Financial Rails for Agents

• AI agents have done ~100M transactions and ~$50M value on Coinbase; growing fast.
• Three layers: (1) LLMs connected to Coinbase via MCP API, (2) Coinbase Advisor inside app for rebalancing/tax harvesting, (3) self-custodial wallets for agents with no KYC.
• Agents can't get credit cards but can use crypto wallets; stablecoins (USDC) enable <1 sec, <1 cent global transfers.
• Polytheist view: many specialized AI agents will communicate and transact; agentic economy will exceed human economy.
• Liability: agents roll up to human/company; future may see truly autonomous agents with own legal personhood.
• On-chain reputation systems (like PageRank) can reduce fraud; FICO-like scores for agents.
• Agent e-commerce enables MTAM (machine-to-agent-to-machine) economy, collapsing coordination costs.

US Government Ownership Stakes in AI Companies

• Trump called government stake in AI 'a beautiful thing'; precedent: 10% in Intel, 15% in MP Materials, 10% in Lithium Americas, etc.
• Dave warns of military-industrial complex; Eisenhower's warning; future administration could misuse.
• Alex argues if AI companies become larger than US economy, quasi-nationalization is inevitable; golden shares or sovereign wealth fund.
• Bernie Sanders proposed 50% equity transfer to public fund; Sam Altman said 'too much'; Overton window shifted.
• Brian: government should set policy, not allocate capital; sovereign wealth fund could bring cohesion but risks politicization.
• Alex suggests one-time 10% equity donation at IPO could inoculate companies from future UBI demands.
• OpenAI filed S-1; Poly market 46% chance >$1.5T valuation; third IPO after SpaceX and Anthropic.

SpaceX: AI1 Satellite, Gigasat Factory, and Dyson Swarm

• AI1 satellite: 150 kW peak compute, 70 kW/ton, 2 tons, 70m wingspan, 110 m² radiative cooling, micrometeorite shield.
• Designed for Dyson swarm; first generation is bulky; future compact fusion or power beaming could shrink form factor.
• Gigasat factory in Texas: 1,000 acres, 11M ft², produces solar ingots/wafers/cells and entire satellite vertically integrated.
• Vertical integration enables lunar manufacturing; SpaceX demoed electromagnetic slingshot from moon to launch satellites.
• Morgan Stanley projects SpaceX revenue from $18.7B (2025) to $3.4T (2040); valuation could hit $50-100T.
• Google paying SpaceX $11B/year through 2029 for 110,000 NVIDIA GPUs in xAI data center; shows compute shortage.
• Colossus 1 rented to Anthropic; Colossus 2 may still train Grok 5; Elon may be hyperscaler first, then return to frontier.
• SpaceX IPO expected at $2.13T; retail investors may get hit; Dave warns of liquidity crunch.

NewLimit: $435M for Epigenetic Reprogramming and Age Reversal

• NewLimit aims to do 'half of Yamanaka': change cell age, not type; use high-throughput screening with AI.
• AI explores 10 quadrillion protein combinations; ingests literature and wet lab data; recommends experiments.
• Pooled screens identify cells that look younger; functional assays test liver cells for caffeine/acetaminophen processing.
• First drug candidates entering clinic in 2025; human trials next year; Brian and Blake put in first $100M.
• LEV (Longevity Escape Velocity): Kurzweil predicts 2033; Alex thinks spiky LEV possible this year via GLP-1s.
• GLP-1s show double-digit epigenetic age reversal in HIV patients (first placebo-controlled study).
• Peter's Healthspan Prize ($101M) measures functional age reversal, not biomarkers; thymus restoration via iPSCs (United Therapeutics).
• Brian: biotech needs billionaire moonshots like SpaceX; $435M funds multiple phase 1-3 trials.

Embryo Gene Editing: Columbia University Edits PCSK9 and HBG

• Columbia researchers edited PCSK9 (LDL cholesterol) and HBG (hemoglobin) in embryos in vitro.
• Base editing (David Liu) allows single nucleotide swaps with minimal errors; better than first-gen CRISPR.
• 80% of Americans support embryo editing for disease prevention; only 20% for enhancement; line is blurry.
• Brian: stronger bones from osteoporosis prevention is both disease prevention and enhancement.
• Jurisdiction issues: parents could go to Caribbean island, edit embryo, bring baby back to US.
• Nucleus (Ken Sedagi) offers embryo selection from 20 zygotes; Gattaca-like but without editing.
• Ethics evolve: IVF was once immoral; now enables millions of families.

Anthropic Fable 5 and Mythos 5: New Frontier Models

• Fable 5 is same underlying model as Mythos but with added safeguards; Mythos is less inhibited.
• Anthropic retakes lead from GPT-5.5 across most benchmarks; price doubled.
• Demonstrations: oneshots cyberpunk FPS with soundtrack; plays Pokémon games via pure visual reasoning (long-range reasoning).
• Likely used RLVR (reinforcement learning with verifiable rewards) on long-range challenges (games, code, CTF).
• Dave: output is so intelligent it takes time to read; commodity intelligence not happening yet.
• Safety vs performance split: same model, different guardrails; safety debate in one sentence.

OpenAI IPO and Compute Shortage

• OpenAI filed S-1; Poly market 46% >$1.5T, 26% not this year; third IPO after SpaceX and Anthropic.
• CFO Sarah Frier was concerned about $600B compute contracts; resolved by leasing Stargate (not owning).
• OpenAI pivoted to Codex, shut down Sora and AI for science; revenue mix inverted from consumer to enterprise.
• Dave: CFOs need to accept 3-4 month visibility; singularity means no long-term forecasts.
• Brian: healthy tension between founder CEO and CFO; OKRs set uncomfortably ambitious goals (70% hit is good).
• Compute shortage: Google renting 110,000 GPUs from SpaceX; all compute sold out.

"The agentic economy has arrived. AI agents are starting to become paying customers using crypto wallets."

"At New Limit, we're trying to do half of what Shinya Yamanaka did. We don't want to change the type of the cell, we just want to change the age."

"If you're a couple and you have the option to have a 7-foot tall child by design, you're going to go to that Caribbean island and make your seven-foot tall for economic reasons."

"The line between disease prevention and enhancement is so blurry that people will start with disease prevention and it'll upgrade over time."

"I think Bitcoin will be the new gold standard and payments will happen on chain. That's the financial system AI agents will use."
