Ask HN: Can we do better than Git for version control?

There are others that are almost as good, I suppose what I should have said is "Can we make something better than GitHub for the hypothetical better non-git VCS", since without that it's hard to imagine using anything but Git.

The current trend (most popular and IMO likely to succeed) is to make tools (“layers”) which work on top of Git, like more intuitive UI/patterns (https://github.com/jesseduffield/lazygit, https://github.com/arxanas/git-branchless) and smart merge resolvers (https://github.com/Symbolk/IntelliMerge, https://docs.plasticscm.com/semanticmerge/how-to-configure/s...). Git it so flexible, even things that it handles terribly by default, it handles fine with layers: e.g., large binary files via git-lfs (https://git-lfs.com) and merge conflicts in non-textual files by custom merge resolvers like Unity’s (https://flashg.github.io/GitMerge-for-Unity/).

Perhaps in the future, almost everyone will keep using Git at the core, but have so many layers to make it more intuitive and provide better merges, that what they’re using barely resembles Git at all. This flexibility and the fact that nearly everything is designed for Git and integrates with Git, are why I doubt it’s ever going away.

Some alternatives for thought:

- pijul (https://pijul.org), a completely different VCS which allegedly has better merges/rebases. In beta, but I rarely hear about it nowadays and have heard more bad than good. I don’t think we can implement this alternate rebases in Git, but maybe we don’t need to; even after reading the website, I don’t understand why pijul’s merges are better, and in particular I can’t think of a concrete example nor does pijul provide one.

- Unison (https://www.unison-lang.org). This isn’t a VCS, but a language with a radical approach to code representation: instead of code being text stored in files, code is ASTs referenced by hash and stored in essentially a database. Among other advantages, the main one is that you can rename symbols and they will automatically propagate to dependencies, because the symbols are referenced by their hash instead of their name. I believe this automatic renaming will be common in the future, whether it’s implemented by a layer on top of Git or alternate code representation like Unison (to be clear, Unison’s codebases are designed to work with Git, and the Unison project itself is stored in Git repos).

- SVN, the other widespread VCS. Google or ask ChatGPT “Git vs SVN” and you’ll get answers like this (https://www.linode.com/docs/guides/svn-vs-git/, https://stackoverflow.com/a/875). Basically, SVN is easier to understand and handles large files better, Git is decentralized and more popular. But what about the differences which can’t be resolved by layers, like lazygit for intuition and git-lfs for large files? It seems to me like even companies with centralized private repositories use Git, meaning Git will probably win in the long term, but I don’t work at those companies so I don’t really know.

- Mercurial and Fossil, the other widespread VCSs. It seems these are more similar to Git and the main differences are in the low-level implementation (https://stackoverflow.com/a/892688, https://fossil-scm.org/home/doc/trunk/www/fossil-v-git.wiki#....). It actually seems like most people prefer Mercurial and Fossil over Git and would use them if they had the same popularity, or at least if they had Git’s popularity and Git had Mercury or Fossil’s. But again, these VCSs are so similar that with layers, you can probably create a Git experience which has their advantages and almost copies their UI.

and the logical history is the filesets which are the nodes in the graph which is the branching sequence of commits

the issue is that the 'logical history' is the reason git was built

and the 'physical history', seems to me, is only feasible because we have the regular git sequence of commits
