Not the person you are replying to but I have, in version control, around 80 projects dating back to about 2008 that are in various states of completion and Claude has been able to resurrect a lot of them and get them from their "half finished but will never complete" state up to "pull in modern dependencies and implement (me giving a list of what remains to be done)" to the point that they are now usable. I'm more focused on the things that are 7 or less years old because anything older than that I'm not sure I have a need for anymore.
