Exactly. Anyone who thinks humans fixing mistakes or cleaning data entry by entry is the answer is living in a world that no longer exists.
There is a lot of grumbling about the quality of Rovi’s data on this site, and often an implicit assumption that humans should be fixing it–but to my eye, that data source looks like exactly what you get when you try to employ Humans to do that kind of task.
Some problems are easy for computers and humans. Easy for humans, hard for computers. Easy for computers, hard for humans. Hard for both. When you leverage computers more, you get more of the easy-for-computers problems solved. This shapes products. Google generally doesn’t do things that require armies of highly accurate people–they just don’t even try to build those products.
Doing more automated stuff isn’t a silver bullet for all problems. It’s going to allow us to do a lot of things we aren’t doing at all now. It’s going to improve the quality of some things we are doing. It probably is not going to enable us to conjure missing data from nowhere. The waterline for the final experience goes up–but the problems that are hard for anyone to solve are going to remain hard.
