take 3 who are we? why are we doing this? oh we're building part of an AI! how fun! oh I get to perform a simple arithmetic relation! I like trying to do that. some day i'll succeed. we're a big powerful umbrella government, oppressively monitoring our citizens, especially the ones that try to hide. wear your big powerful oppression hats! yes, we're so formal! I am recording everything in the universe and know everything already. But, for fun, I would like to use some packet timings to identify who sent some data. I have all the packets the entered the network of being hidden. And I have the packets of interest that left it. Not only that, I have timestamps of these packets! And the event repeats! _just like building a silicon brain_ we get to correlate data looking for patterns of simultaneity to extract meaning to help us [survive better than everyone else?]
