I believe that software engineering hasn't disappeared; it's just that the act of writing code is losing its former central role.

The biggest change in my work over the past year isn't increased efficiency but that many things I used to think I had to do manually are now too lazy to do myself.
Writing tests, updating documentation, refactoring repetitive logic, debugging—many times I just hand it over to AI.
At first, I was a bit uneasy, checking line by line, but gradually I started letting it write first, run it, and only fix if something's wrong.
This change is actually a bit scary because I suddenly realize I'm shifting from a code creator to a code reviewer.
In fact, many times I can't even remember if a certain piece of code was written by me or not.
And I found that when everyone can use the same AI tools, the gap between people becomes even more obvious.
Some generate systems; others generate disasters.
Later, I gradually realized that what truly becomes valuable is changing—not syntax, not frameworks, not even a particular language itself.
It's whether you truly understand the business, whether you know why the system is designed this way, and whether you can predict if it will crash later.
AI can help you write code, but it can't yet take responsibility for the consequences.
