Software isn't what it used to be
The creator of Node.js, one of the most-used software frameworks in the world, said it last week: the era of humans writing code is over.
Developers are becoming tool builders, not code writers. AI coding agents are taking over the writing. For businesses: custom software that used to take months now takes days.
2.7 million views. And he's right.
What does that actually mean?
"Developer" no longer means writing code.
And if you think about it, a developer was never really about writing code. It was always about building tools.
For a long time, writing code was simply the best way to do that. Not anymore.
The best way to build tools now is with AI coding agents: Claude Code, Codex, Cursor, and others.
There's going to be a split
I think developers are going to fall into two clear camps:
- Those who adapt to this new reality
- Those who refuse to accept it
You have to think about what you're really doing. What's the higher purpose?
The Netflix parallel
Netflix used to be a DVD rental service.
If they'd said back then, "we want to be the best at delivering DVDs to people's homes", nobody would have heard of them today.
Instead they realized what they were actually doing: making home entertainment as easy as possible.
That's why they could make the jump to streaming. That's why they're so big now.
For developers and for businesses
Same thing's happening with developers now.
If they cling to "writing code" as their thing, they'll get passed by.
What they're really doing is building tools.
The skills they've spent years building (understanding systems, architecture, spotting when something's wrong) are extremely valuable right now. They're the best-placed people to build tools with AI.
But they have to make the transition.
Why this matters for your business
If you run a business, this changes everything.
The cost of custom software is dropping fast. Tools that used to need a full dev team can now be built in days.
That means: you no longer have to choose between expensive custom software or gluing together 15 SaaS tools.
You can just build what you need. Tailored. Fast.
The bottom line
Ryan Dahl said it. The best developers I know say it.
The era of humans writing code is over.
But the era of humans building tools? That's only just beginning.
Lean in.
Frequently asked
What does "the era of writing code is over" mean?
Developers now use AI coding agents (Claude Code, Cursor, Codex) to build tools instead of writing code by hand. The role shifts from code writer to tool builder, the same way Netflix shifted from DVDs to streaming.
What happens to developers?
Developers split into two camps: those who adapt and use AI tools to build faster, and those who refuse. The skills developers have (understanding systems, architecture, spotting problems) stay valuable. They're now applied with AI as the accelerator.
Why does this matter for my business?
The cost of custom software is dropping fast. Tools that used to require a full dev team can be built in days. You no longer have to choose between expensive custom software or gluing together 15 SaaS tools. You can just build what you need. Tailored. Fast.
