Nothing is certain. The apps you love can be removed by developers or app stores at any time. The music you enjoy can disappear from streaming platforms, since you only rent access while you listen. The selection of shows and movies you stream can change anytime. Social media platforms rise and fall every decade, and when monetization fails, companies collapse. This is the reality of the world today.

But it doesn't have to be that way. We can still choose to buy CDs, vinyls, cassettes, and movies. Games are the tricky part since you can't buy new games offline any more, but retro games still exist. Open source can last forever, as long as we keep backups or host our own repositories. We can build our own tools, run our own websites, and host our own instances. But even that doesn't guarantee longevity, because everything still relies on one thing - you. When you die or lose interest, your creations fade with you.

Ironically, I've seen countless websites and apps come and go over the past 30 years. Yet my blog is still online, just as it was when it started as an "online journal" back in 1998. I've always focused on longevity. But that's not the main point. The real point is understanding that not everything is in our control. And that is worth keeping in mind. Every single day is precious. We should touch grass sometimes.

Memento mori.
