IC product lifetime as function of junction temperature

If an IC is rated for an absolute maximum junction temperature of say 170 Celsius, obviously it is not recommended to operate there - but how drastically is product lifetime impacted if we are close, say operating at junction temperature of 160. How severely does the IC lifetime get shortened as we get closer to the maximum junction temperature ?

There are two rules of thumb when it comes to premature aging of electronics and temperature:
Every 10°C above 25°C halves its life
Every 15°C above 25°C halves its life.
The 10°C is derived from a certain application of Arrhenius' equation
$ AF = e^{ frac{E_a}{k}}(frac{1}{T_{use}}- frac{1}{T_{test}}) $
The issue with this is the 10°C result was a very broad interpretation of the empirical results (no consideration was given to other failure modes).
MIL-HDBK-217 took into account field data and concluded that 15°C is a figure more applicable to practical usage
