Re: "RESET"

I don't quite understand the need for "reset" buttons on products.
 
That function is always available by cycling power -- even for devices
where that is difficult for the user (e.g., PoE, BBU, etc.)
 
Shouldn't a device be able to get itself out of a "pickle" without
requiring the user to intervene?  Particularly devices that are
intended to "run forever"?
 
I.e., it seems like the presence of a reset button is a tacit admission
that the engineering is "lacking"...

Sometimes it is the user that is lacking.  Such as forgetting a
password. Maybe putting the device in the wrong mode and can not
remember how to get it out of that mode.

With the many lines of code it  is impossiable to check out every
possiale combination of things that could ge wrong in a reasonable time.

While not really much of a chance but in the eairly days bits could be
randomally changed by stray radiation.
