Building on the [React integration](https://panel.holoviz.org/reference/custom_components/ReactComponent.html) I quickly discovered that since mapping parameters in Python to React state was such a simple problem, LLMs would go a long way. Using a simple prompt, I was able to bootstrap a comprehensive set of components and their respective React implementations.

While nice in theory, the UX of a fully automated wrapper library will always suffer, and the initial AI generated component-set I had generated was no different.\n", + "\n", + "Once the basic structure was in place, we went to work and reviewed, cleaned up and documented each component in detail.

The idea being that the transition to panel-material-ui should be as easy as possible and that when we eventually replace the original Panel components as part of the Panel 2.0 release, there will not be a major transition either.
