What is an AI agent, really?

Not every script that calls an LLM is an agent. A true AI agent is an automation system that takes a process and carries it out using AI, making decisions, calling tools, and handling multi-step workflows, rather than just returning a single model response. Much of what's marketed as 'agents' is simpler LLM API plumbing dressed up by hype.

Why do most AI agents fail in production?

Because demos are built for the happy path. Real workflows are full of edge cases, messy data, and reliability requirements that brittle agent setups can't handle. Even Apple (which pulled back AI summarization over hallucinations) and Amazon (Alexa integration) have struggled. Reliability, not capability in a demo, is the hard part.

Should my business build an AI agent?

Only after a clear assessment: define the specific problem and check whether it truly needs an agent's flexibility or could be solved with simpler automation; run a cost-benefit analysis that includes ongoing model costs and maintenance; verify you have clean, structured data and the right team; then roll out in stages, starting with low-risk internal use before anything customer-facing.

Should AI agents replace employees?

The most successful implementations augment human workers rather than replace them, creating human-AI collaborative workflows that combine an agent's speed and consistency with human judgment. Aiming straight for full replacement is where many projects over-reach and break.

Where do AI agents actually deliver value today?

In specific, well-scoped vertical workflows with clean data and clear success metrics, not as general-purpose assistants. Narrow scope is what makes them reliable enough to trust, and it's also where the largest business opportunity lies (see the $300B vertical AI agents thesis).
