Long-running systems inevitably face wear and tear issues.
The structure of BitTorrent allows some nodes to age and exit without causing fatal impacts on the overall system.
The network does not rely on a certain group of "core nodes" to exist permanently, but rather maintains overall vitality through continuous replacement.
This tolerance for wear and tear means the system does not need to be regularly restarted or upgraded as a whole.
Each node replacement is part of the network's self-updating process.
When a system can withstand long-term wear and tear without collapsing, its lifespan is naturally extended significantly.
