The internet is a tool of communication, nothing more.
The owner of an internet forum I sometimes visit thanked all their supporters announcing their forum was their legacy to the world. “Fool,” was my immediate thought. Legacy in my opinion means something tangible left to others in the material world: a planted tree, children, a business, a work of art. The internet is an ephemeral medium, only a fool would think anything can last more than a few years on the internet.
The internet is a fast-moving medium. Information posted to the internet exists only whilst the host, the server, the electricity that powers the internet lasts. Millions of customers of Kim Dotcom lost their business and personal information when a host erased it from their servers, millions more fear the same fate awaits them after their information fell into the hands of government agencies.
To me the internet is a tool of communication, an advance upon the days when Native Americans communicated with each other with smoke signals from a fire. Unless the internet ever became conscious, the moment when your computer develops an attitude and answers back if you swear at it, the so-called moment of singularity, the internet will only ever be a tool of communication. Even if we reach the moment when the internet can run our homes, offices and cars, it is still a mere communication tool making this happen. The internet reality check is an awareness the internet is a mere clever communication tool, nothing more. People build legacies in the real world, never the internet.
