"rubber" compounds are attacked by "silicones". The other 
concern about
using silicone around electronics is that one of its 
properties is a very
high dielectric strength. Given its propensity to creep, 
that could be a
problem on the various contacts.

     I think this is backwards. High dielectric strength 
means resisance to arcing, i.e., good insulating qualities. 
I think the bulk resistance of silicone rubbers is also high 
meaning it should be good stuff around contacts.

         Not sure why we need anything different than has 
been used on them
for the last 50 years.

    Well, consider that older lubricants had a strong 
tendency to become gummy and lose their lubricity. More 
modern lubricants are both better lubricators and last very 
much longer.
    You want something that will maintiain efficient 
operation of the parts, reduce wear to a minimum, have a 
long operating life, and not damage anything. Modern 
lubricants do better at all of these than the older ones.
