The most valuable skill in 2026 isn't writing code. It is deleting it.
TL;DR
In 2026, AI makes code generation easy, but maintenance costs remain high. The most valuable skill is deleting unnecessary code to reduce complexity and improve clarity. Focus on subtraction, not addition, to create efficient systems.

We are currently living through the greatest inflation of software in history.
With the AI tools we have available in 2026, a Junior Developer can generate more lines of code in an afternoon than a Senior Developer used to write in a month. We have lowered the barrier to entry for creation to almost zero.
But we have not lowered the cost of maintenance.
If anything, we have created a crisis. We are drowning in "good enough" code, boilerplate, and features that "might be useful later."
Code is not an asset. It is a liability.
I used to measure my productivity by how many green squares I had on my GitHub contribution graph. I thought that writing more meant I was building more value.
I was wrong.
Every line of code you write is a commitment. It is something that needs to be:
- Tested
- Debugged
- Secured
- Updated when dependencies break
- Read by the next person (or yourself in 6 months)
The Hoarder Mindset
I recently realized that my codebase looked exactly like my "Read Later" list—a graveyard of good intentions.
I had features I built "just in case." I had abstractions that were "future-proof" (for a future that never arrived). I had utility functions that were used once and then forgotten.
It was digital hoarding. And just like hoarding physical objects, it creates a mental load that paralyzes you.
The Era of the Code Janitor
The best developers I know right now are not the ones spinning up 10 microservices in a weekend. They are the ones walking into a project and saying:
"We can delete this module."
"We don't need this library."
"We can solve this without code."
They are not Architects. They are Janitors. And I mean that with the highest possible respect.
The Art of Subtraction
I spent this past weekend doing nothing but deleting.
I removed a feature that only 2% of users touched but caused 50% of the support tickets.
I ripped out a complex state management library and replaced it with standard React hooks.
I hard-coded variables that I had made dynamic "just in case."
The result? The bundle size dropped. The build time was cut in half. But most importantly, my mental model of the system became clear again.
Conclusion
In a world where AI can write infinite code, the value of writing code approaches zero. The value shifts entirely to curation.
Your job is no longer to build the mountain. Your job is to carve the sculpture out of the rock.
If you want to be a Senior Engineer in this new era, stop asking "What can I add?" and start asking "What can I remove?"
Go look at your PRs from last week. Did you add complexity, or did you remove it?
The most satisfying commit message is not "Feat: Added X".
It is "Refactor: Deleted 2,000 lines".
