I have been integrating AI into my coding workflow for over two years. In this field, two years is a lifetime. I’ve seen the "wow" moment of the first GitHub Copilot suggestions, and I’ve seen the limitations of early LLMs that hallucinated libraries that didn't exist.
But something shifted in the last few weeks.
I’ve been deep-diving into the recent updates of Cursor IDE and Antigravity IDE, and the conclusion is inescapable: we have moved past the era of "smart text prediction." We are entering the era of the Autonomous Engineer.
The Shift: From "Start" to "Plan"
Just a month ago, AI Agents were fantastic at the "Greenfield" phase. If you gave them a pristine directory and a very specific, hand-held walkthrough, they could spin up a new project faster than any human. But you had to be the architect; they were just the bricklayers.
The recent updates have flipped this dynamic. The new Planning Modes in tools like Cursor aren't just waiting for code snippets; they are capable of:
- Ingesting a high-level goal.
- Breaking it down into comprehensive tasks.
- Writing their own walkthroughs.
They are no longer just following instructions; they are helping write the instructions.
Conquering the "Brownfield"
The biggest hurdle for AI coding has always been context. It’s easy to write a script from scratch; it is infinitely harder to jump into a 50,000-line codebase, understand the state management, respect the linting rules, and implement a feature without breaking six other things.
The new generation of IDEs has solved the context window problem to a frighteningly effective degree. I watched these tools navigate my existing, complex projects, fixing bugs and adding features with an awareness of the broader architecture that I previously thought only a human could maintain.
The "Senior Developer" Analogy
This is the most profound realization I’ve had this week.
In the past, using AI felt like managing a Junior Developer. You had to check their work constantly, explain the same concepts three times, and sometimes just rewrite the code yourself because it was faster.
Now? It feels like I am sitting at the head of a table with a team of Senior Developers.
Consider the traditional workflow:
- We hold a meeting to discuss project plans.
- The team goes away.
- Two weeks (or a month) later, we meet again to review the deliverables.
With the current state of Cursor and Antigravity, that timeline has collapsed. I talk about the project plan, and the "team" implements it right on the spot. There is no "delivery next month." The meeting is the implementation.
The Trajectory is Vertical
What excites me—and perhaps terrifies me a little—is the trajectory.
If the leap from "Junior Dev" to "Senior Dev" happened in the last 6 months, where are we going to be 6 months from now? The speed of improvement isn't linear; it feels exponential.
We are no longer just coding faster. We are orchestrating logic at the speed of thought. The barrier to entry for building massive, complex software is dissolving before our eyes.
If you haven't updated your toolkit in the last month, you are already falling behind. The Seniors are ready to work—are you ready to lead them?
