Changing of the Guard

12/4/2025

For the last fifteen years, Silicon Valley has been run by the Cartographers.

These were the Product Manager founders. Their craft was the interview, the survey, the carefully meticulously prioritized roadmap. They viewed the world as a known continent. Their job was to find the muddy paths (the inefficient workflows, the messy Excel sheets) and pave them.

The playbook was sacred: Talk to your users. Feel their pain. Build a solution. Iterate.

It was a game of empathy. If you listened hard enough, the customer would tell you exactly what to build. They would ask for a button here, a dashboard there, a slightly faster horse. And if you built it, you won. You built a great SaaS company. You optimized the world.

But the map has changed. Or rather, we have sailed off the edge entirely.

We have entered an era where the raw materials of software — intelligence, reasoning, generation — are advancing faster than human imagination can track. In this new world, the Cartographer is useless. You cannot ask a customer for directions to a place they do not know exists.

We are entering the age of the Magician.

The Spell of Structure

The old world of OCR (Optical Character Recognition) was about pixels. "How do I get this text out of this image perfectly?" Customers asked for higher accuracy, faster processing.

Reducto didn't look at the customer; they looked at the model. The two 23 year old founders realized that the consumer of text is no longer a human. It is an LLM. And LLMs don’t like messy text; they like structure. They like Markdown.

Before Reducto, developers were just shoving raw PDFs into context windows and praying. The results were garbage. Reducto didn't just build a tool; they invented a best practice. They invented the modern document processing market. They proved that the path to intelligence wasn't PDF → LLM, but PDF → Markdown → LLM.

They fundamentally altered the data pipeline for an entire industry. They didn't build a "better OCR." They built a translation layer for machines. They realized that the problem wasn't "reading text," it was "feeding brains."

The Spell of Omniscience

The same blindness afflicted the IDE.

If the Cursor team had followed the standard SaaS playbook, they would have built a VS Code extension. That’s what users asked for. "Just give me a plugin," the developers said. "I don't want to switch editors."

A Cartographer would have listened. GitHub Copilot listened. They built a nice inline editor for code completion. It was safe. It was reasonable. It is dead.

The Cursor team didn't listen. The 24 year old founders understood something the users didn't: to make AI truly magical, it needs to see everything. It needs to know where your cursor is. It needs to see the linter errors before you do. It needs to index your entire codebase and hold it in its mind.

So they did the "wrong" thing. They forked the entire IDE. They took on a mountain of technical debt and friction.

They didn't build a faster text editor. They built a pair programmer, letting anyone write software with ease. You talk to the AI, and it writes the code for you.

The Spell of Absence

But in this market, magic fades fast.

Just as Cursor convinced the world that the IDE must be rewritten, Claude Code arrived to argue that the IDE should not exist at all.

If Cursor is a faster car, Claude Code is teleportation.

Anthropic realized that if the reasoning is strong enough, you don't need a GUI. You don't need tabs or file trees or syntax highlighting. They intentionally constrained users to a terminal—a "worse" UX by traditional standards—because they had such high conviction in their agentic capabilities.

They bet that a developer doesn't actually want to edit code; they want to complete tasks.

This is a bet that no user would ever ask for. "Please take away my interface for a lackluster terminal UX" is not a feature request. It is an active rejection of user preference, rooted in the fundamental belief that there is more beyond the horizon. It is a belief that the real end user of software engeering is not a human. It is a rapidly improving AI agent.

Claude Code is a harness for intelligence. They didn't build an interface for the user; they built a workspace for the agent, and simply added a window for the human to watch.

The Magician's Curse

This is the Changing of the Guard.

The moat is no longer your sales team. It is no longer your "sticky workflow." It is your technical audacity.

The founders winning right now are not the ones with the best user interviews. They are the ones who are deep in the latent space, reading the arXiv papers at 2 AM, tinkering with the weights, asking: What if?

In this market, it is a bloodbath of magic experiences. You cannot just be "one and done." The spell that works today will be a parlor trick tomorrow.

This is why the next wave of giants will be built by founders under 25. The veterans are too wise. They know too much about how software "should" be built. They are burdened by the physics of the old world. They would never fork an IDE. They would never delete it entirely.

The young have no such burden. They don't know what is impossible. They only know what is magical.

You cannot discover the future in a customer support ticket. You have to conjure it.

So stop asking for permission. Stop waiting for the survey results to come back. The people you are trying to serve are riding horses, and they are happy. They have no idea what is coming down the road.

Show them what only you can dare to imagine.
