The code is only a small subset of the network.
In fact the code's resistance to change is a feature of the network itself.
One that provides a foundation of stability, security, and trust.

• How many corporations, governments, and billionaires will join the network over the next ten years?
• How many more Bitcoin ATMs will there be?
• How many permissionless second-layer solutions will be devised?
• How many other networks will wrap Bitcoin and connect to it with their services?
• How far will renewable energy explode into the future when producers of said energy can turn the excess into money instantly on site without having to store it in a battery or connect it to the monopolized grid?
• How many phone apps will utilize the network?
• How much liquidity will their be?
• etc etc etc

These are all pieces of the network.
While the code may look the same in 10 years the network/applications certainly won't.
