blog: Multitasking is dead. Parallelism is rising.

What/Why/How?

Adds the blog post "Multitasking is dead. Parallelism is rising." at blog/rise-of-parallelism.md.

The post makes these points:

• Multitasking research from the 2000s is correct. One person who splits attention across two tasks pays a switch cost.
• Starting a second agent is not multitasking. It is parallelism. An agent is a worker, not a task. The person holds the queue, not the tasks.
• The skill moves to the aim. The pitch is the aim, the agent run is the flight. Review the pitch, not the flight. A pitch is small and cheap to review. The output is large and already committed to the pitch's assumptions.
• Fear of starting several agents is a signal that the first one was not aimed.

Open questions for review:

• Categories. No category in blog/metadata/blog-metadata.yaml covers how we work with agents. The post uses technical-documentation:ai-assisted-docs and redocly:product-updates. Suggest a better pair if one exists.
• The H1 ends with a period, so the file carries a markdownlint-disable-next-line MD026 comment. Remove it if the title changes.

Overview

Adds a new blog post titled "Multitasking is dead. Long live parallelism." (blog/rise-of-parallelism.md) along with its header image (blog/images/rise-of-parallelism.png). The post explores the difference between human multitasking and AI agent parallelism, arguing that managing concurrent agents shifts the primary human skill to upfront task framing and pitch review rather than active context switching.
