You're Writing Code. Seniors Are Reading It

 Un buen artículo de W3Schools:

 Watch a senior developer for a day and you'll notice something strange. They barely type. They read. Pull requests, logs, old functions, AI suggestions, docs they already read twice.
Reading is the job. Writing is what happens after.
And it's almost never taught on purpose.
The skill that quietly runs everything

Every tutorial is about writing. Every bootcamp project is about building. Even practice platforms give you a problem and ask you to produce a solution. When you fail, the failure is framed around the code you wrote, not the code you read.

But real development work looks different.

You spend more time reading code than writing it. Reading what your past self shipped six months ago. Reading what your teammate merged at 2am. Reading a stack trace that makes no sense yet. Reading AI-generated code that arrived instantly with complete confidence and zero context.

In 2026 the imbalance is getting worse, not better.

AI can produce fifty lines before you finish your coffee. The bottleneck has moved. The question is no longer "can you write this?". It is "can you tell if this is right?"

That is a reading skill.

And almost nobody trains it on purpose.
The second phase most people skip.

The bottom line: the best developers are not the fastest writers. They are the most careful readers

This hits different when you are reviewing AI generated code before it goes live. It looks clean. Logic seems right. Tests pass, Then you actually read it and catch the edge case that would've silently broken a client's workflow at 3am. AI writes confidently for the average case. Reading is how you catch what confidence missed.
The bottleneck really has shifted.
