HOW IMPORTS WORK IN RSC

React Server Components (RSCs) extend JavaScript's module system to span both client and server, using directives like 'use client' and 'use server' to clearly define where code runs. Instead of copying code between environments, these directives act like controlled entry points, while “poison pills” like server-only or client-only imports prevent accidental leaks by causing build-time errors. This creates two separate but connected module systems, allowing safe code sharing and controlled data flow between frontend and backend.

Shopify discovered that JavaScript import maps were too fragile for real-world use. They would break if any modules loaded before them or if multiple maps existed on the same page. Working with web standards experts, Shopify developed and implemented a reconciliation mechanism that allows multiple import maps and modules to coexist safely, which shipped in Chrome 133 and Safari 18.4.

WHY GO IS A GOOD FIT FOR AGENTS

Go is a good fit for building AI agents due to its concurrency model, channel-based communication, centralized cancellation mechanism, standard library, and excellent profiling tools. Go's simple concurrency allows for efficient handling of many long-running agent processes, while channels facilitate asynchronous message passing.

WHY AGENTS ARE BAD PAIR PROGRAMMERS

Current LLM agents make poor pair programmers because they code too quickly for human collaboration. Instead, they are better for asynchronous workflows like code review or in slower, turn-based modes.
