Windows is not able to offer a consistent native UI over a decade.

The UI inconsistency in Linux was created by design.

MacOS is no longer the safe heaven where designers can work peacefully.

Electron Apps have , but they also lack off visual consistency and keyboard-driven workflows.

Some restartet from scratch with Dart and Flutter UI to replace Android legacy things. Google gave up because they needed a monopoly or a large enough market to succeed.

Zed did the same thing in Rust: they designed their own cross-platform GPU-renderer library. It lacks integration with the host OS on itself though.

On the contrary, TUIs are fast, easy to automate and work reasonably well in different operating systems.
