In my experience the code will, but by year 5 nobody is left who worked on it from inception, and by year 10 nobody knows anybody who did, and during that time it reaches a stage where nobody will ever feel any sense of ownership or care about the code in its entirety again.

I come into work and work on a 20 year old codebase every day, working on slowly modernizing it while preserving the good parts. In my experience, and I've been experimenting with both a lot, LLM-based tools are far worse at this than they are at starting new greenfield projects.

This conversation shows how diverse the field is!

When it comes to professional development, I've almost never worked on a codebase less than 10 years old, and it was always [either silently or overtly] understood that the software we are writing is a project that's going to effectively live forever. Or at least until the company is no longer recognizable from what it is today. It just seems wild and unbelievable to me, to go to work at a company and know that your code is going to be compiled, sent off to customers, and then nobody is ever going to touch it again. Where the product is so throwaway that you're going to work on it for about a year and then start another greenfield codebase. Yet there are companies that operate that way!
