We know that the Jedi are essentially extinct and defeated at the end of III (or soon after). But we don't know how this happens. One thought I'm beginning to have...does technology ultimately bring about the defeat of the Jedi? Do their ways and their powers become obsolete? We are already seeing this with General Grievous, who appears to be nearly unstoppable. If the Separatists have one weapon to defeat the Jedi, who is to say that they don't have more? And who is to say that the Empire does not adopt this technology? One of the running themes in Star Wars is the battle between nature and technology. We see this contrast in Vader himself, who is part man, part machine. The whole planet of Naboo is a contrast in technology vs the primitive. In ANH, there is a very open discussion on board the Death Star about the relative merits of technology and the Force. The general view of the Imperials is that the Force is an outdated and useless tool from the past. And finally, we see the triumph of nature in ROTJ, when the primitive Ewoks help to defeat the mighty Empire. I am wondering if, to complete this circle, the forces of evil in Ep III use technology to defeat the Jedi. Almost like an arms race of sorts, with the Jedi ending up on the losing end of things, their way of life wiped from the galaxy. In episode I and II, the Jedi are almost like supermen. But if technology were developed to render their lightsabers and perhaps Force powers useless, they could be eradicated quite easily.
