One trend that sci-fi authors, role playing games, movies and multiuser environments have talked about for decades, is finally becoming more and more real.
Examine these parallel trends:
A. Dungeons & dragons / Role playing (non-computer) characters
-> text MUD games players
-> MMORPGs (e.g. Ultima Online, Everquest, World of Warcraft)
-> Non-RPG-based environments (The Sims Online, Second Life)
-> Military Tactical/Strategic representations
-> Telemetry and Remote Imaging
-> Battlefied information systems
-> Robotic military (Remote guided aircraft/UAV, bomb-detection robots, etc.)
C. Heroic Mythology (Greek myth, Viking sagas, Chinese myth)
-> People with secret super-hero identities (Batman, Daredevil, Spiderman)
-> Robotic personas (Voltron, Gundam & Macross series)
-> Virtual worlds (Tron, The Matrix trilogy)
D. User accounts
-> Web home pages
-> individual blogs
-> Group content/documents (wikis, forums, chats, etc.)
-> Spaces (combining Web pages, blogs, other Web 2.0 services)
-> Online personas
While different in form and utility, what it is pointing to is a change in how we perceive our identities in the rise of the online/alternate world.
Call them what you like, your blog, your avatar, your character, your robot, your role in the Matrix... It all points to having a separate identity for yourself in an environment other than the one you live in right now.
I tend to see this as a continuing trend where we will see more and more of ourselves participating in the online world on a regular basis.
However, I also think that people will start making distinctions. Most of us have different faces even in a typical day: there's a similar but distinct persona of you at home, at work, at school, with your family, with your friends, with the government, etc.
They are all you, just different aspects of you. With the online world, it's easier to make those different aspects, or even create new ones based on the online environment.
This comes back to developers in a real way. There is probably a "developer" identity that you put on (some of the time, or even much of the time for others).
What that developer identity needs is a environment of its own. In fact, traditionally we have that too:
> assembly language
-> programming languages
-> compilers & other developer tools
-> integrated development environments
-> online searching
-> online code repositories and exchanges
-> online group projects and identities
The X here is where it all comes together into an online space that is yours and that you have your developer avatar participate in, and that can interact in an online community or virtual world with many other developers.
In this virtual world, we're not talking about a game of fighting other developers (aka WoW style), but in a real sense of getting involved in projects, learning new ideas or meeting new people who are working on things you are interested in. It gives the setting for participating.
Once someone builds that participation environment, you as a developer can suddenly see or be exposed to the many opportunities that lie ahead. This opportunity can translate into dollars and jobs in the real world.
