Look at it this way: colleges can't control a student's internal motivation. But they can control how they structure class time, and how they intervene with troubled students. So they're focusing on what they can control instead of what they can't.
Although, I think that well-timed intervention can help students with motivation problems. Students tend to lose motivation when they're struggling and don't know how to improve.
The tools are all there and I agree that some good will come out of it. But without a motivation to learn something, I don't see these technologies as being a solution. More of an amplifier of a solution than anything else. Start ups focused around creating technology to measure students seem like a good way to make the above "quadruple click back button for success" scenario play out somehow.
