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.

> Visual Studio does a decent job of abstracting the GIT nuances, but I personally use GIT Extensions, which looks and feels much better on Windows than the other cross platform UIs.

IDEs and text editors sometimes have nice Git integrations in the UI, but I wanted standalone software that I can use for anything from various programming projects, to something like gamedev projects (with Git LFS) or arbitrary documents.

In the end, I just forked over some money for GitKraken, it's pretty good, especially with multiple accounts on the same platforms, when you want to switch between them easily: https://www.gitkraken.com/

There's also Sourcetree which I used before then, kind of sluggish but feature complete: https://www.sourcetreeapp.com/

For something more lightweight, I also enjoyed Git Cola on various OSes: https://git-cola.github.io/ Even Git documentation has a page on the software out there, a good deal of which is free and has good platform support: https://git-scm.com/downloads/guis

Quite frankly, I spend like 90% of the time using a GUI interface nowadays, when I want to easily merge things, or include very specific code blocks across multiple files in a commit, or handle most of the other common operations. Of course, sometimes there's a need to drop down to the CLI, but you're right that some GUI software feels like it actually improves the usability here.
