In some ways, I'd say we're in a software dark age. In 40 years, we'll still have C, bash, grep, and Mario ROMs, but practically none of the software written today will still be around. That's by design. SaaS is a rent seeking business model. But I think it also applies to most code written in JS, Python, C#, Go, Rust, etc. There are too many dependencies. There's no way you'll be able to take a repo from 2026 and spin it up in 2050 without major work.

One question is how will AI factor in to this. Will it completely remove the problem? Will local models be capable of finding or fixing every dependency in your 20yo project? Or will they exacerbate things by writing terrible code with black hole dependency trees? We're gonna find out.
