Relates to a thing I was wondering about: suppose a process runs for time T before terminating and we know distribution of T. What can we infer about internals of system knowing nothing other than this distribution? If not exponential can we can infer it has some internal state

Another example: a non-exponential failure time for a machine tells you its state is changing, eg. from wear and tear. Exponential suggests (to me at least) wear-and-tear isn't the issue.

Replying to and
fixed time would mean there's a quantity being used up internally, then the "early or late" failure pattern of hard disks implies a number of bad apples, etc
