I understand your feeling
Nobody likes it if being told what they do is idiotic and got no purpose.
Like I said, no harm done.
Who am I to deny you the pleasure of thinking
you are saving electricity and prolonging the lifespan of the equipments by using auto-timer.
Machines dies faster the longer you run it,
this I agree for washing machines.
Modem/router has no moving parts,
they die faster due to thermal stress, meaning fluctuation of temperatures.
By the way,
MTBF (Mean time between failures) means the average time taken to replace faulty equipments.
Not average lifespan.
bruised your ego? sorry.
Had to correct you there. MTBF is not the average time taken to replace faulty equipments.Nobody likes it if being told what they do is idiotic and got no purpose.

MTBF is time between failures (assuming repairs/replacements are done).
i.e., System A runs 3 years before failing -> repair -> runs 2 years before failing -> repair -> runs 1 year before failing
MTBF (average time between failures) = (3+2+1)/3 = 6/3 = 2 years
But I agree with you where equipment without moving parts do not die faster from running them longer. Temperature spikes are a more likely cause of failures since small parts being used nowadays can be quite temperature sensitive.
