Heh, that's an interesting thought that i've also sometimes had.

For doing something like that, the hardware would need to be way more resilient and have failover for various components - for example RAID for the HDDs/SSDs and some mechanism for clustering and failover for apps and other stuff you'd want to run on them. But even with those in place, i'm not sure that the hardware that's available to us wouldn't just die long before the 100 year mark.

Anyone have any idea what are the oldest computers presently in continuous use? Best i could find was this, but it was just turned on for once, instead of being continuously working: https://www.smithsonianmag.com/smart-news/watch-the-worlds-o... Apart from that, all i can think of are mainframes and such.

I really doubt that any piece of currently modern hardware could last 100 years without becoming some hard to understand mess that's incredibly out of touch with the OSes and paradigms of the future. What would you even run on it? Debian? FreeBSD? Haiku? Would there be anyone to debug Python 2 or Python 3 in 100 years? What about Java, .NET, PHP, Golang, Rust, C++ or even C? Considering that many of those ecosystems are more and more migrating to integration with the Internet, especially for the dependencies, what are the chances that any of the software will survive that long?
