Once more your exburance of youth shines through! It's so lovely.
Can I give you something to think about.
When I was 17 I used to talk with and argue with my father over many things
in life. It surprised me when I was 17 just how stupid my father was and
how little he knew.
When I was 22 I still used to talk with and argue with my father over many
things in life. Only we argued much less. I was amazed how much he had
learned in only 5 years !

Well I've yet to see anything non-trivial be error free and I've only been
writing software for 23 years. That's writing software to pay for feeding a
family for 23 years. Takes deep breath... in that time I've produced
software that powers the machines that performed about 25% of the world's
biopsies, about 70% of the world's cervical smears, been part of the team
that produced the state of the art multi role SONAR that is used by the
UK's nuclear submarine fleet (about 5 millions lines of C, 750k lines of
assembler & 15millions lines of ADA), 2 Bluetooth stacks, a video over IP
data manager, MPEG4 video codec and a content rendering system for mobile
phones (only shipped about 50million copies of this).
So yes, there is no such thing as a non-trivial error free program!
