AI Fundamentals: Stripping Away the Jargon

TL;DR

• AI isn't magic: it's just advanced pattern recognition.
• Generative AI (like ChatGPT) creates content but can't act.
• AI agents are the next step, giving AI "hands" to perform tasks.
• The real opportunity is moving from talking to AI to having AI do work for you.

What AI Really Is - Spoiler: It's Not Magic

Machine Learning is pattern recognition on steroids. Feed a computer enough examples of cats, and it learns to spot cats in new pictures. Show it enough chess games, and it gets decent at chess. It's not thinking—it's finding patterns in data, then applying those patterns to new situations.

Think of it like teaching your younger sibling to recognize your mom's car in a parking lot. After seeing it hundreds of times, he knows what to look for: the dent in the fender, the specific shade of blue, the bumper sticker collection. ML works the same way, except instead of one sibling, you have millions of computational processes examining millions of examples.

This isn't new. Credit card companies have been using ML to catch fraud for decades. Netflix uses it to recommend shows you'll binge-watch at 2 AM. Amazon uses it to predict what you'll buy before you know you want it.

The Generative AI Shift - Computers That Write

Generative AI changed everything by flipping the script. Instead of just recognizing patterns, it creates new content based on those patterns. It's the difference between a critic who can spot a Basquiat painting and an artist who can paint in Basquiat's style and energy.

Large Language Models (LLMs) like ChatGPT are basically very sophisticated autocomplete systems. They've read most of the internet and learned to predict what word comes next in any sentence. Ask them a question, and they generate an answer by predicting the most likely sequence of words that would follow your question.

Here's what's wild: this simple "predict the next word" approach somehow produces responses that seem thoughtful, creative, even insightful. It's like teaching someone to cook by showing them every recipe ever written, then watching them invent new dishes.

But here's the catch—and it's a big one.

The Action Problem

LLMs can write poetry, debug code, explain quantum physics, and compose resignation letters. But they can't actually send that resignation email, deploy that code, or order the ingredients for that recipe.

They're brilliant consultants trapped in a conversation. They can tell you exactly what to do, but they can't do it themselves.

This is like having the world's smartest friend who lives in a soundproof booth. They can give you perfect advice through the intercom, but they can't open doors, make phone calls, or grab you a coffee. Great for brainstorming, useless for execution.

Enter the agents.

Agents: AI That Actually Does Stuff

AI agents are what happen when you give that brilliant trapped friend a set of hands, access to your tools, and permission to use them.

An agent combines an LLM's intelligence with the ability to interact with the real world through APIs, databases, and other systems. It can make decisions, take actions, remember what happened, and adjust its approach based on results. Engineering leaders and junior developers take note. The foundation for how AI Agents work is built on top of APIs, databases, and all that boring stuff everyone keeps saying does not matter any longer. It still does, and will continue to (more to come on this in future posts).

Think of coding assistants in agent mode. The old chatbot version would analyze your code and suggest fixes, but you had to copy-paste everything yourself. The agent version examines your codebase, identifies the problem, writes the fix, tests it, and commits the changes—all while you grab coffee.

While this cannot be defined as true intelligence, the difference is profound. It's the jump from having a really smart research assistant to having a capable employee who can work independently.

For agents to work, though, they need plumbing—connections to systems and standards that let them act reliably.

The Plumbing: APIs and MCP

None of this works without proper plumbing. APIs (Application Programming Interfaces) are the standardized contracts that let different systems talk to each other without knowing each other's internals.

For example, instead of scraping airline websites and trying to decode their HTML (a nightmare), travel sites use airline APIs that provide clean, structured access to flight data. It's the difference between trying to eavesdrop on a conversation through a wall versus having someone hand you a transcript.

MCP (Model Context Protocol) is the emerging standard that lets agents interact with these APIs systematically. It's like having a universal translator that helps agents understand and use any tool they encounter. Think of it like a standard power outlet—you don't need a different plug for every house you visit. Or Lego bricks that always snap together. Or Wi-Fi that just works no matter the laptop. The idea is one simple standard replaces dozens of custom connectors.

Without MCP, every agent would need custom integration with every service. With it, agents can plug into new systems as easily as you plug a USB device into your laptop.

Agent-to-Agent: The Network Effect

Here's where it gets interesting. Individual agents are useful, but networks of specialized agents are transformative.

Agent-to-Agent protocols let different agents discover each other's capabilities and collaborate. A travel planning agent might discover a restaurant recommendation agent, learn what it can do, then delegate the dinner research while focusing on flights and hotels.

Imagine a team of specialists who can instantly understand each other's expertise and seamlessly hand off work. Your personal assistant agent realizes you need tax help, finds a tax specialist agent, confirms its capabilities, and delegates the entire tax preparation process.

This isn't some distant future—the protocols exist today. We're just waiting for the ecosystem to mature.

Why This Matters Now

We're at an inflection point. The technology has moved beyond party tricks and into genuinely useful territory. But most people are still thinking in terms of chatbots and autocomplete.

The real opportunity isn't in having conversations with AI—it's in having AI handle entire workflows on your behalf. The people who understand this first will build significant advantages.

Smart engineers are already experimenting with agent frameworks. Smart managers are identifying processes that agents could automate. Smart investors are backing companies that treat AI as infrastructure, not novelty.

The question isn't whether agents will transform how we work—it's whether you'll be ready when they do.

A Practical Takeaway

Start simple. Pick one repetitive process in your work that involves multiple systems and clear decision points. Map out the steps, identify the APIs involved, and imagine how an agent might handle it.

For example, an engineer could automate log analysis: instead of manually scanning logs for errors, build an agent that pulls logs from a database, flags patterns, and files a ticket automatically. A manager might automate weekly status reports: have an agent pull metrics from Jira, Slack, and GitHub, then generate a clean summary for the team.

Don't wait for perfect tools. The best way to understand this technology is to experiment with it. Try building a simple agent to automate something annoying. For engineers, start with a code-based approach like this tutorial Building AI Agents in Pure Python↗. If you're looking for a no-code option, check out this tutorial The AI Agent Tutorial That Should’ve Been Your First↗ (no-code with n8n).

The future isn't humans versus AI—it's humans with AI agents versus humans without them. The real value will come from experimenting early, learning the limits, and steadily finding practical wins.
