The claim to fame for SawStop is Not stopping the blade, but Sensing when
your pinkie finger touched the blade and Then stopping the blade before
you lose said pinkie.

Can't agree, that technology had been around for many years. I have lamps
in my house that turn off when touched, building elevator buttons that
select by touch, and my I-phone needs the touch of skin, not a stylus or
finger nail to work.


Getting a blade spinning in excess of 3000 rpm to stop in a small fraction
of a turn and drop below the table surface is the tricky part.
