Alot of Viruses or Bacteria remain dorment for some time before unleashing attacks, though for a very short time, these viruses are still spreading from one person to another though various orifice including the one behind into the sewer, and if they monitor the sewer they can catch something like this early in the group of population and hence a preventive measure before the next pandemic
Yes, the above was just in someone’s head during pandemic era
But then, they were able to also determine stress level in a given population with a study done in China from sewer water Link to paper in Pubmed
Your shit reflects what you eat, what you feel and underlying health conditions
For now, you are anonymous among the group of people living in the same town so they cannot exactly tell you apart from other’s sewer. But what if they find a way to shitprint where they can uniquely identify you from the shit you just dumped? Maby just a way to extract DNA from your shit stuff.
Maby if you are a wistleblower or someone the government would want to keep track of, they may somehow engineer a biological weapon that does not harm but will replicate itself just enough for it to be released from behind and let them know where you are.
Again, this is a far fetched and frankly stupid. But our current surveillance reality was just as stupid a decade ago.
I can imagine data brokers trying to get into the sewers to gather health data for advertisement far in the future. So I guess the only viable alternative would be to build septic tank to fight such surveillance like we currently do with selfhosting to protect our data. Just like we dont let these corporations get the hold of our data willingly, should we let our sewers get into their hand?
Dogs are able to casually identify the individual who produced the most minute sample of shit, tell you their last three meals, what they are going to die from, and when; and dog society didn’t fall apart. We’ll manage.
I have a English pit I’ve had since she was a very little pup. Early on I noticed that there were times when she seemed distressed. She would come nose punch me in the leg and whine and paw. As time progressed, I discovered she was actually predicting my seizures. At first I thought it coincidental, but the accuracy was just too uncanny to dismiss. I have read that before a person has a seizure, they emit a certain chemical odor that the dogs can sense. My lady friend also says my demeanor changes before I have a seizure, and my pit may also be picking up on those cues. She’s never had any formal training, it’s just something she does and I am grateful.
That’s because the technology is socialized and every dog can use it. If only the dog ruling elite were able to tell that, you’d have a dog dystopian police state.
So, it all reduces to a prior problem. The sewers are a red herring.
