I spent last weekend building an AI agent that books my flights, compares hotel prices, and…

sends me a summary email. Took me 14 hours.

Two years ago, that would've taken a team of three and two months.

Here's what nobody's talking about with agentic AI — it's not the technology that's hard. LangGraph, CrewAI, AutoGen... the frameworks are mature. The hard part is designing the failure modes.

My flight-booking agent confidently tried to book a $12,000 first-class ticket because I didn't set constraints properly. That's the real engineering challenge — not "can it do the task" but "what happens when it does the task wrong."

The agents that win in production aren't the smartest ones. They're the ones that fail gracefully.

If you're getting into agentic AI, spend 30% of your time on the happy path and 70% on everything that can go wrong. Trust me on this.
