The Stack — July 04, 2026

Today's technology briefing highlights significant developments across AI/ML, industry moves, infrastructure, and the developer world.

AI/ML

A new programming paradigm called "Program-as-Weights" (PAW) has been introduced, which compiles functions from natural language into neural artifacts. This allows for efficient, offline execution with minimal memory usage, offering an alternative to direct large language model prompting. This innovation could enhance AI efficiency in various applications.

Industry Moves

Meta is facing challenges in its AI development efforts, with slower-than-expected progress in AI agent development despite significant investments. Meanwhile, the browser market is seeing a shift towards AI integration and privacy features, with new AI-powered browsers offering chat-based search engines and automation capabilities. Privacy-focused browsers continue to emphasize user data protection.

Infrastructure

In the semiconductor sector, startup Etched has announced the production of its first chip by TSMC, with plans to ship systems powered by it later this summer. However, scaling production may be challenging due to limited capacity at TSMC's factories. Copper Sky Capital, an early investor, is considering moving production to TSMC's Arizona facility to address these constraints.

Cybersecurity

A new macOS malware named PamStealer has been discovered, highlighting a growing focus on developing information-stealing software targeting Mac systems. This underscores the need for enhanced cybersecurity measures specifically for macOS.

Developer World

Valve has open-sourced the e-ink screen for the Steam Machine, enabling users to create their own displays through a project named "Inkterface." Additionally, a new version control system called Oak has been introduced, designed to optimize latency and efficiency for agentic software development while maintaining compatibility with existing Git workflows. This reflects ongoing innovation in open-source hardware and software development tools, emphasizing transparency and improved workflow efficiency.
