This is primarily the work of Alex Syrel. The project was initially financially sponsored by ESUG and it is currently supported by feenk. And of course, the project is based on the tremendous work that went into Bloc and Brick by all contributors.

For example, the last example shown in the video is an editor opened on 1M characters, which is reasonably large, and as can be seen see one can interact with it as smoothly as with the one screen text. It actually works just as fine with 100M characters.

Currently, the editor is 1260  lines of code including method and class comments. This is not large for a text editor and this is possible because most of the work is done by generic concepts that already exist in Bloc such as layouts and text measurements. Beside the small maintenance cost, the benefit is that we have the option to build all sorts of variations with little effort. That is why we call this a moldable text editor.

The underlying structure (https://en.wikipedia.org/wiki/Rope_(data_structure)) is theoretically thread-safe, but it still needs to be proven in practice.

Please also note that because now Bloc is directly embeddable in Morphic it means that we can actually start using it right away. For example, the picture below shows the text element being shown through a live preview in the GTInspector.

There is still a long way to go to reach that goal, but considering the work that is behind us, that goal that looked so illusive when Alain and Stef initiated the Bloc project is now palpable.
