We distinguish ourselves, and apes, as higher order creatures by (among other things) the ability to create and use tools.
Creating a jig is no different than the creation of the screwdriver, hammer, chisel, etc etc etc. Using a jig is no more cheating than is using a ladder to clean your gutters, or a ruler to draw a straight line.
I see a lot of shortcomings with this device that the sawstop doesn't have:
Auxiliary miter fences
box join jigs
any jig with a high fence component.
SawStop doesn't suffer from any of those issues since the sensor is via the blade and not a cumbersome hood device (that seems to also be obscuring vision from the front).
It's a nice entry level safety device, but it's not up to what sawstop can do.
@WaltB - I'm pretty sure the reason the actual finger tests are done slowly is because even with Saw Stop, injury can occur. If you activate your saw stop system it's still going to hurt like hell, and it's NOT a GUARANTEE against injury. I'm pretty sure that no one's going to want to slap his hand down on a spinning blade.
If you don't like the inventor demos, just look up all the "saves". Those people were all using it normally.
