IBM's CTO Mark Dean, one of the original engineers that created the IBM personal computer, is convinced that the post-PC era is already here. Mark believes that technological innovation is driven not by devices, but by the social interaction that these devices enables.
"My primary computer now is a tablet," Dean wrote in his blog post. "When I helped design the PC, I didn't think I'd live long enough to witness its decline. But, while PCs will continue to be much-used devices, they're no longer at the leading edge of computing. They're going the way of the vacuum tube, typewriter, vinyl records, CRT and incandescent light bulbs."
Computing is becoming not only more personal, but also more social, he said.
"PCs are being replaced at the center of computing not by another type of device -- though there's plenty of excitement about smart phones and tablets -- but by new ideas about the role that computing can play in progress," Dean wrote. "These days, it's becoming clear that innovation flourishes best, not on devices but in the social spaces between them, where people and ideas meet and interact. It is there that computing can have the most powerful impact on economy, society and people's lives."
Dean's comments echo those of some other industry executives.
