It already is. By it's nature, computers are an accessibility tool. I work as a programmer for the State of Maryland who uses accessibility software and hardware. JAWS, Dragon Naturally Speaking, ZoomText, and so on. There's also modified hardware like one-handed keyboards, tablet-PCs with screen pens (for those with mobility issues), braille printers, braille readers (both software and hardware - one that pops up little pins in a braille pattern on a keyboard-like thing). There's even "echo-location" (for the lack of a better term) devices for the blind that sends out pings when someone walks by. I've heard it whenever I walk by. Even the software/webpages we create must be accessible (i.e., screen readers should be able to read them) by law, and it's tested to be so. There's even accessibility software built into the operating system (screen magnification, virtual keyboard, etc.). Anyway, here's what I think... CPUs and storage devices will continue to advance. I think there's a bit of a plateau for computer speed, monitor quality, even memory (4 gigs really isn't that different than 2 gigs... unless you're using Vista or something). I had 1 gig 10 years ago. Gaming may see advances with the introduction of better AI chips, physics chips, and other specialized chips. More portable peripherals like the iPod, iPhone, will be created. That's where the technology will be. (I think the Gameboy back in the late 1980s was a pioneer in handheld technology! ) As for things like the Google OS, I still doubt that we'll be seeing online operating systems or applications in mass use.
