Amazon is expected to start informing employees about sweeping job cuts starting today. It plans to lay off as many as 30,000 staff across its corporate workforce. The layoffs are part of a broader cost-cutting campaign that started during the COVID-19 pandemic. Amazon CEO Andy Jassy said earlier this year that the company's workforce could shrink further as a result of generative AI.

SAM ALTMAN REPORTEDLY DEVELOPING NONINVASIVE BRAIN INTERFACE TO RIVAL ELON MUSK'S NEURALINK

Sam Altman's Merge Labs is a brain-computer interface (BCI) startup. It recently hired an award-winning biomolecular engineer, Mikhail Shapiro. Shapiro's past work suggests that the startup could be aiming to create a device that could link to the brain using sound waves. If Merge Labs is successful, its device may be preferable to Neuralink's BCI as it wouldn't require surgery.

WHY IP ADDRESS TRUNCATION FAILS AT ANONYMIZATION

Truncated IP addresses are still personal data under GDPR, especially when combined with other information that most systems routinely collect. Subnet size doesn't correlate with user anonymity. The network prefix itself contains enough information for trivial identification. Many organizations are creating compliance risks by thinking IP truncation is GDPR-compliant anonymization. What is actually needed is encryption specifically designed for IP addresses.

MORE BIG COMPANIES BET THEY CAN STILL GROW WITHOUT HIRING

Companies in the US are increasingly making the calculation that they can keep the size of their teams flat, or even shrink them, without harming their businesses. Part of this is the belief that artificial intelligence will be used to automate more processes, but companies are also hesitant to make moves in an uncertain economy. The widespread caution in hiring is frustrating job seekers and leading many employees within organizations to feel stuck in place. Operating with fewer people can pose risks for companies by straining existing staff or hurting efforts to develop future leaders.

SPEEDRUNNING AN RL ENVIRONMENT

RL environments can be surprisingly complex and fun to create. This post explains what RL environments are, introduces the 'verifiers' framework, and also walks readers through how to create an environment for a benchmark called AgentDojo. RL environments are scenarios that LLMs operate in for evaluation or training. Designing them means essentially defining the maze, the rewards, and how the LLM navigates through it.

AI DISCOVERS NOVEL CANCER DRUG, OR DID IT?

Google recently published an announcement that its Gemma model had discovered a new potential cancer pathway. It's important to note that the model didn't invent or theorize a method to discover potential drug candidates - the entire construction of the experiment was imagined and executed by humans. The model was used to probabilistically narrow a set of potential candidates to a manageable set that could be inspected by human review. Humans still possess a reasoning capability that is not present in any current AI system.

RATE-CUT OPTIMISM FUELS $921M IN GLOBAL CRYPTO FUND INFLOWS

Crypto investment products saw $921 million in weekly inflows, rebounding sharply from the prior week's $513 million outflow. The increase was driven by rate-cut optimism after lower CPI data and strong US demand, with Bitcoin funds adding $931 million, their largest gain since rate cuts began, while Ethereum products saw $169 million in outflows, their first dip in five weeks. Trading volumes held strong at $39 billion, well above average, and inflows were led by the US ($843M) and Germany ($502M).

STABLECOIN LINKED CARDS - WAY BETTER SECURED CREDIT CARDS

Stablecoin-linked cards allow users to spend USDC or USDT at any Visa/Mastercard merchant through instant fiat conversion at point of sale. Self-custodial options like Ether.fi allow users to borrow against crypto collateral at 4% APY while earning 10% yield. Revolut's zero-fee stablecoin conversion for 65 million customers and Coinbase's Bitcoin-backed loans powered by onchain protocols like Morpho demonstrate how vaults are bringing decentralized lending to mainstream fintech apps, replacing balance sheet lending with private credit models. The shift toward direct stablecoin acceptance by merchants and banks will compress settlement times to zero, eliminating the 1-2% early payment fees merchants currently pay and the up to 2% consumer on/off ramp costs.

This shift enables fully autonomous AI agents and lets API providers design new onchain business models where data, compute, and services can transact seamlessly in real time.

A NEW PATH FOR PROPRIETARY AMMS

Proprietary AMMs managed by professional market makers have captured 40%+ of Solana trading volume by updating pricing curves up to 74 times per second, enabled by extremely cheap updates compared to swaps that allow market makers to achieve Top of Block priority with minimal fees and avoid front-running. EVM's expensive storage writes versus swaps create only a 1:10 ratio instead of Solana's 1:1000, making updates costly and vulnerable to arbitrageur front-running since outbidding requires only 10x the priority fee. A proposed solution combines a Global Storage smart contract for price curve parameters with a builder policy that reserves the first 5-10% of block gas exclusively for these updates ordered by priority fee, creating a protected "fast lane" that guarantees Top of Block execution and establishes a local fee market competing only against other updates rather than all DeFi transactions.

LOCKONOMICS

Velodrome and Aerodrome – the leading DEXes on Optimism and Base – pioneered "lockonomics," a model where users lock tokens for up to 4 years to receive voting power, protocol fees, and project bribes, while LPs receive token emissions instead of direct fees. The system imposes a "speculation tax" on short-term holders through inflation that benefits lockers – currently 50% of supply is locked with an average duration of 3.6 years – and can be stabilized via emission control to match revenue when growth slows. Velodrome currently runs 15% annualized inflation while delivering 20%+ APY to lockers, deliberately operating at emissions exceeding revenue to drive sticky growth through accumulated protocol-owned liquidity and user lock-in before eventually reverting to a sustainable emissions-equal-revenue equilibrium.

WTF IS ORCHESTRATION (OR CLEARING) (OR SETTLEMENT)

Orchestration (coordinating between parties), clearing (reconciling who owes what), and settlement (actual fund transfers) evolved in traditional finance to coordinate transactions across networks of intermediaries maintaining separate ledgers. Crypto's multi-chain reality has recreated the same coordination challenges that shaped traditional finance, despite blockchain's promise of instant settlement on a single shared ledger. The opportunity lies in rebuilding these functions through smart contracts, cryptographic proofs, and programmable liquidity rather than institutional intermediaries, creating systems that are more performant, upgradeable, and transparent to handle crypto's expected orders-of-magnitude higher velocity of money.

NETFLIX GOES ‘ALL IN' ON GENERATIVE AI AS ENTERTAINMENT INDUSTRY REMAINS DIVIDED

Netflix is embracing generative AI as a production tool. CEO Ted Sarandos maintains it won't replace creative storytelling, citing recent uses in shows like "The Eternaut" and "Happy Gilmore 2" for visual effects and de-aging. The streaming giant's AI adoption comes amid industry-wide concerns about job displacement and unauthorized use of artists' work in training data, with recent controversies involving OpenAI's Sora 2 model generating deepfakes of actors. Despite positioning itself as "all in" on AI technology, Netflix reported quarterly revenue of $11.5 billion, falling short of its forecast despite 17% year-over-year growth.
