Multi-mode fiber could be the computer cable connection of choice in the distant future. It's been used inside data centers for years where very high speed data transfer was needed between equipment.
The cable itself is cheap and it's fairly easy to connectorize, and generally doesn't need expensive test equipment like single mode fiber (which is used for long haul). The transmitter and receiver are still relatively expensive although prices have drastically come down over the years, and I'm sure the prices will continue to come down.
As more and more fiber to the home is installed I'm sure at some point the speed of the inside wiring will need to keep up.
