And will all contractors need to install SawStop on their older
machines, or else subject themselves to being sued by any worker using
their tool? A worker will end up having to supply his own tools, if
push comes to shove.

I would imagine liability insurance would be less costly for an
employer using SawStop or other safety improvements. Airbags have
similarly affected auto insurance -- cost of physical damage to car or
property was and is minor in comparison to medical and liabilty costs.
