The SawStop has a bypass mode allowing you to cut metal or other conductive materials. While in the bypass mode it also shows you (until the motor is off) if anything you cut has triggered the safety. This allows you test-cut wet or green wood to determine if its able to be cut using the SawStop module.
There are many professional carpenters who have bought the SawStop not because they were unsafe, but because they used the tool predominately to make a living. Added security in a medium-low income profession.
I think they're a great idea when used by a professional who is going to take the same care on every cut that he did before he installed it. I can certainly understand the motivation to save yourself downtime from an injury when you are using the thing all day every day. I just don't think they're a panacea for the student shop environment in the way that they often get promoted. Kids aren't always going to test the wood, or remember to turn the bypass off after they're done, etc.
Then again, I also think people should learn to drive in cars without automatic transmissions, traction control, or antilock brakes.
