In a recent discussion about the value of deleting code, one specific habit kept coming up: leaving blocks of commented-out code in a file, just in case we might need it later.

We all know we should not do it. We have version control systems that remember every keystroke we have ever made. Yet, we leave that graveyard code right in the middle of our active files. We do it because deleting feels permanent, and keeping it feels safe. But in reality, it just transfers the cognitive load to the next person trying to read the file.

This habit of hoarding code is just a symptom of a much larger problem. We are a generation of digital hoarders.

The cognitive load of "read-it-later"

Look outside your IDE. Look at your browser with its forty open tabs. Look at your read-it-later app, filled with hundreds of articles, tutorials, and deep dives that you saved months ago. We hoard this information with the best of intentions. We tell ourselves that we will read it this weekend.

But we rarely do. Instead, that infinite list of unread links becomes a source of low-grade anxiety. It transforms from a library of knowledge into a visual reminder of everything we are failing to keep up with. It is the exact same cognitive load as the commented-out code, just applied to our daily lives.

Embracing digital decay

The solution to both problems is the same: we need to embrace the concept of decay.

In nature, things that are no longer useful break down and clear the way for new growth. In software and personal knowledge management, we try to keep everything alive forever. But if a piece of code was truly important, you will write it again, probably better. If an article was truly essential, the concept will cross your path again.

We need to stop treating every piece of digital information as a compounding asset. Most of it is temporary context.

This specific realization is actually what pushed me to build my own tool recently. I was tired of feeling guilty about my endless list of saved links, so I built Sigilla. It is a bookmarking tool with a very specific constraint: unread links decay and disappear over time. If you do not read it, the system cleans it up for you. No graveyard, no endless backlog, just the things you actually have the time and intention to focus on right now.

Whether it is a block of legacy code or an article about the latest framework, the most liberating thing you can do is to let it go. There is beauty in letting things decay.
