If my phone is able to avoid losing almost all of its standby time
without me having to care about whether my bouncing cow game was written
by a complete fool or not, that means that my phone is *better* than one
where I have to care. Would the world be better if said fool could be
sent to reeducation camps before being allowed to write any more
software? Probably, but sadly that doesn't seem to be something we can
implement through code. I'd love it if we could assume that all software
is going to be perfect, but in the absence of that ideal world there's a
strong incentive to develop technology that does its best to cope with
adverse situations.
