I disagree.
Automation, especially audio automation, is extremely important.
Some examples:
When recording real musicians playing real instruments, you don't just
 record one take, you record several takes, then pick the best one and 
 use the others to patch up the odd mistakes within the best take.
Without automation, it is impossible to do this.
It is easy to say "just cut and paste the corrected takes into the best take",
 but this is not good because you cannot just place the tail end of one
 wave up against the beginning of another wave - you will get a 'pop'.
(Advanced apps might do the joining for you, with averaging or filtering).
With audio automation, you do a quick, but not sudden, fade out of the
 best take at the correction point, and simultaneously do a quick, 
 but not sudden, fade in of the corrected take. Then you do the reverse
 when the end of the corrected take arrives.
This makes the transitions sound smoother.

If the editing is done on the waves themselves, that's destructive
 and when your session ends, well, you're stuck with those waves.
(Non-daw claims to have unlimited 'go-back', but I've not tested this).

You also want to be able to correct a track with a portion which is just
 a bit too quiet or a bit too loud, without editing the waves themselves.
I would say not altering the original waves is most important, to me.

Apart from that, even simple song fade-outs are impossible without
 automation, unless you like to do everything by hand, 'live' as the
 song is playing.

There are many cases where automation is required even in the simplest
 of songs. If none of the linux mid/audio apps had automation, I would 
 certainly have given up! I would not have been able to produce 
 my songs without it.
