In Richard Brautigan's poem "All Watched Over by Machines of Loving Grace", what kind of figures of speech does he use? I know one of them is sarcasm, but I can't figure out if there are any more...

Satire is a literary term, but sarcasm is not.

Look through all these definitions and see what you find. Generally, the most commonly used in all literature are these, so check these out first:
simile
metaphor
alliteration
assonance
synecdoche
personification
hyberbole
