A lot of engineering discussions focus on frameworks.
Far fewer focus on system boundaries.
The framework will change.
The architecture probably will too.
Clear boundaries between services, modules, and ownership tend to outlive both.
Noticed something interesting this week.
Every feature request sounded urgent.
The analytics said otherwise.
Before building anything new, I now ask:
How many users asked for it?
How often does the problem occur?
What metric should improve?
Saves a lot of engineering time.
Talked to a founder who spent 3 months building an AI feature.
Users barely touched it.
The feature they requested most?
Export to CSV.
A reminder that customer interviews are usually a better roadmap than assumptions.
The boring requests often make the biggest difference.
Claude Fable 5 scores higher than any publicly released AI model.
Last month, it found bugs that had been hiding in software for 20+ years.
Scenes at every org right now:
