> You have an ideological approach instead of a practical one.

It's both. We can save a whole lot of time and money not wasting resources on security theater and reallocate it towards efforts that actually make society better and safer.

> It isn't governments that are demanding it. I am demanding it of our government, I and the majority.

> I don't want freedoms paid for by such intolerable and abhorrent levels of ongoing injustice. It isn't a false sense of security, for the victims it is very real.

No, it still is a very false sense of security. Intercepting illicit material online doesn't actually stop the crime from being committed nor does it dissuade people from distributing it.

> Most criminals are not sophisticated. Crime prevention is always about making it difficult to do crime, not waving a magic wand and making crime go away.

Sure, but the 'criminals' that are distributing illicit material online are already going to lengths, sometimes very technical, to distribute it anonymously.

> I'm not saying let's give up freedoms, but if your stance is there is no other way, then freedoms have to go away.

You are saying let's give up freedoms. Let's drop any sort of notion that you care about freedom because you do not. I'm not saying that it's an invalid world view; your reasoning for wanting to eradicate those freedoms is rational and with good intention, but you are begging for authoritarianism none the less.

I don't think there's any sort of agreement to be had here. Fundamentally I cannot agree with the notion that everyone must concede their personal liberties and privacy in order to capture a few more stupid criminals.

> But my stance is that the technology is there, it's just slippery slope fallacy thinking that's preventing from getting it implemented.

No, it's actually just a slipper slope. There is no fallaciousness in the logic here because we've already witnessed the erosion of our rights for this purpose over and over again and they continue to push for even more degradation of those rights.

> Persons aren't identified before a human reviews and confirms that the material is illicit.

This is already a violation of privacy. Share all of your personal photos with hacker news if you disagree. We don't know who you are, after all, so it's not a violation of your privacy, right?

> There is just cause, the material was flagged as illicit. In legal terms, it is called probable cause. If a cop hears what sounds like a gunshot in your home, he doesn't need a warrant, he can break in immediately and investigate because it counts as extenuating circumstance. The algorithms flagging content are the gunshots in this case. You could be naked in your house and it will be a violation of privacy, but acceptable by law. If you said after review, they should get a warrant from a judge I'm all for it.

In legal terms, probable cause is what you need to make an arrest or before obtaining a search warrant. The "gunshot" exception isn't probable cause. It's an emergency exception that allows for a warrantless search because there is an independent, externally observable signal of imminent harm i.e. an emergency situation.

The algorithms are not the 'gunshot' here. It is not searching in response to some sort of external signal like a gunshot or hearing someone screaming or even seeing someone getting attacked. It is the search itself - it only produces a flag marking someone as suspicious because it has already examined someone's private files. The "probable cause" was produced by conducting the search. That is backwards.

It is equivalent, in your analogy, to a cop opening every front door in the neighborhood to look inside and then saying they now have probable cause because they saw something suspicious. The search already happened.

> It is materially false, because that the scanning can be done without sending a single byte of the device. The privacy intrusion happens not at the time of scanning, but at the time of verification.

You do not need to transmit information for it to be violation of privacy. If a cop opens your filing cabinet, looks through your folders, and leaves everything exactly where he found it, he's still already intruded by examining your private material.

The suspicion of criminal activity must precede the search. Simply possessing digital files isn't a basis for individual suspicion - you are treating everyone as a suspect that deserves no protection.

> To continue my example, the cop could have heard you playing with firecrackers, you didn't do anything wrong but your door is now broken and you were probably naked too, which means privacy violated. This is acceptable by society already.

Society accepts warrantless entry only when there is an actual emergency - The reason a gunshot or firecrackers can justify it is because they are external signals - they do not require the police officer to enter the home in order to detect it.

Society does not accept random entries just to look for problems.

And just to get ahead of it, a machine performing the search doesn’t change anything. A search is defined by what’s being examined, not who (or what) is doing the examining. If the government sent a robot into your home that didn’t know your name and only alerted authorities if it found something illegal, it would still be a search. The fact that it’s automated doesn’t make it any less of an intrusion.

Let me post a longer reply later. But for your last point, we do have automated machine generated alarms in form of smoke detectors. We're legally required to have them in our homes. Firefighters might do the breaking in though, instead of cops, but still agents of the government. Is it more accurate to treat internet access, same as public road access? it's a regulated privileged, instead of a right. You can't taint your windows too much so cops can look in for example when driving on public roads.

With this logic, you could justify embedding cameras in every private space of someone’s home. The feed could be sent to a server running an automatic algorithm that flags potential crimes. If something suspicious appears, authorities would be alerted and an independent review would determine whether a crime occurred.

I have no doubt in my mind if we did that it would certainly be a huge win for law enforcement, detecting crimes and gathering evidence to help catch criminals. Why stop there, though? Why not require everyone live in glass apartments like in the novel We?

These aren't big leaps from what you're proposing. You are advocating for mass surveillance with the assumption that these systems won't be abused despite countless examples of surveillance being misused by those in power.

Comparing scanning all of someone's digital files to smoke detectors is absurd.
