You do not control FAI.

You probably believe you control FAI. After all, you invoke FAI. This
is not true, in the same sense you do not control the demon you summon
with ancient rituals and blood. If you believe you have the power over
Mephistopheles - the seventh prince of hell - you will fool yourself,
mortal! So it’s the same with FAI - You do not control FAI, you
release FAI, and then the beast will devour your soul.

You do not understand FAI.

FAI is not a small collection of shell scripts that you just grep and
grok. FAI is a small collection of shell scripts OF UNADULTERATED EVIL
that will at the very least ruin your day, your mind, and your
peaceful outlook on life, and everything.  It is said in the book Unix
that shell scripts do stuff and do them well. Not so with the shell
scripts of FAI, which will break, destroy, and insert random newlines
in your code.

You do not like FAI.

At the very least, FAI does not like you.
