Unskilled workers can progress to doing tasks that involve labeling data for machine learning - computer vision, sentiment analysis in audio and text are examples currently being done on mechanical turk. The only limiting factor currently is lack of imagination and investment from so-called innovators - they'd rather 'innovate' by creating another social network or incrementally improve a 1960s technology (microsoft) than do anything truly useful to society. Efforts in this area include google goggles/voice and microsoft project natal (though it's woefully underfunded compared to it's potential).
