Spoon
I'm not familiar with Pijul, and haven't finished watching this presentation, but IME the problems with modern version control tools is that they still rely on comparing lines of plain text, something we've been doing for decades. Merge conflicts are an issue because our tools are agnostic about the actual content they're tracking.
Instead, the tools should be smarter and work on the level of functions, classes, packages, sentences, paragraphs, or whatever primitive makes sense for the project and file that is being changed. In the case of code bases, they need to be aware of the language and the AST of the program. For binary files, they need to be aware of the file format and its binary structure. This would allow them to show actually meaningful diffs, and minimize the chances of conflicts, and of producing a corrupt file after an automatic merge.
There has been some research in this area, and there are a few semantic diffing tools[1,2,3], but I'm not aware of this being widely used in any VCS.
Nowadays, with all the machine learning advances, the ideal VCS should also use ML to understand the change at a deeper level, and maybe even suggest improvements. If AI can write code for me, it could surely understand what I'm trying to do, and help me so that version control is entirely hands-free, instead of having to fight with it, and be constantly aware of it, as I have to do now.
I just finished watching the presentation, and Pijul seems like an iterative improvement over Git. Nothing jumped out at me like a killer feature that would make me want to give it a try. It might be because the author focuses too much on technical details, instead of taking a step back and rethinking what a modern VCS tool should look like today.

I built a dashboard to display this for the design system I work on at my day job to give product designers better visibility into this, using a library called react-scanner[0] and some logic related to the way our different product repos are structured. there are probably other libraries for this sort of thing in different ecosystems, and you can always build your own with a parser as well.

Project mention: Show HN: DotLottie Player – A New Universal Lottie Player Built with Rust | news.ycombinator.com | 2024-04-04The current release supports >95% of the animations on our community contributed free animations library. No changes required! We open-sourced a tool called relottie ((https://github.com/LottieFiles/relottie) to detect unsupported features in a Lottie for this player (and other players) to help folks build a validation step in their CI/CD.
We are making frequent contributions and releases on ThorVG and dotlottie-rs to get to 100% support!
