People like to bash it but few realize the challenge of creating brand new purpose-built design system from scratch that can work at scale and complexity of AWS.

Is it perfect? No (what is perfect though?) Not a lot of people have been around long enough to understand how bad the situation was prior to Polaris (internal name for Cloudscape). On top of it, the team that owns it is highly competent and opinionated (hey Boris) and they are committed to support and evolution of it.

When I’ll have fitting use case, I will use it in a heartbeat in my own projects.
