Agents
AI agent
AI agents promise autonomy — but deliver orchestration dressed as agency.
AI agents are not intelligent beings. They are programs built to pursue goals using tools and external environments — often steered by LLMs, augmented with memory and planning. Their real utility lies in narrow automation: booking travel, handling support tickets, drafting ads. But they do not yet operate safely or reliably beyond those bounds. The architecture is decades old. The hype is new. The gap between promise and practice remains wide.
An AI agent is defined by goal pursuit, tool use, and autonomous action — not by intelligence or consciousness.

How it runs
LLMs drive its decisions, but memory, planning, and orchestration layers make it more than a chatbot.
3:24
Where it delivers
It automates discrete, API-accessible tasks — like travel booking — where failure modes are contained.
4:37
Where it comes from
The 1990s BDI model laid the groundwork — this is not new architecture, but a new stack layer.
5:58
Old theory, new substrate
Cybernetics and Selfridge’s 1958 Pandemonium paper established the idea — long before LLMs existed.
7:22
The autonomy illusion
It replaces scripting with goal specification — but only works when the environment doesn’t fight back.
Worth your time?
Yes. Study the whole thing.

The written brief1 min read
What it is and the problem it solves
An AI agent is an autonomous program that solves the problem of open-ended task execution: booking travel, managing support tickets, or drafting policy — all from a single prompt. It replaces rigid workflows with adaptive, iterative action.
How it works
An AI agent is a program that pursues goals, uses tools, and acts autonomously. Its control flow is frequently driven by large language models. It may include memory components, planning logic, tool interfaces, and orchestration software.
What works
Task automation works in constrained settings: booking travel plans from a user’s prompt; assisting developers; triaging customer queries; routing government service requests; generating ad copy. These rely on stable APIs, predictable inputs, and bounded error tolerance.
What does not
It does not reliably perform complex, high-stakes, multi-step tasks outside narrow domains. Safety, alignment, security, and efficacy concerns remain unresolved. Widespread practical implementation has not materialised beyond coding, customer support, government services, and advertising.
What it changes
It shifts automation from linear scripts to goal-directed, environment-modifying behaviour. It reorients software design around orchestration, memory, and tool use — not just output generation.
Is it worth your time
Not yet for most operational use cases. Real-world deployment remains limited as of mid-2025. The gap between theoretical autonomy and reliable, safe, multi-step execution is still wide.
