The unintended consequences
While I would oppose these laws regardless, a much larger concern here is the fact that "Operating System" is not defined in any of these laws. Without the law itself restricting what type of operating system it is talking about it therefore, as written, applies to all operating systems. While I suspect that the lawmakers think OS refers only to home computers, if so, it shows that they don't understand the technology that hope to regulate.
So, for example:
1.) Every motherboard has a BIOS. Which is an operating system that is used by computers to initialize hardware. These systems are not designed to have user accounts and really should not be connected to the internet, but this law would seem to require that every new motherboard to implement user accounts, an age verification system, and a connection to the internet, and an ability to integrate with app stores. Seems a bit much for a motherboard.
2.) Every Television technically has it's own operating system. Dumb TVs and most monitors have extremely simple Operating Systems that just let it change channels, adjust basic settings, and relay data from external devices for streaming. Smart TVs, however, allow for user accounts and age verification. Based on the wordings of the laws, all Dumb TVs and most monitors will be illegal to sell because they lack age verification.
3.) Every router and every modem has it's own operating system. These do tend to be internet connected, but routers are not always used to connect to the internet. They are often kept offline on purpose for local intranets. Requiring that they connect to the internet for age verification would cripple the security of most government offices.Even if this was not a concern, the introduction of user accounts into a router and modem adds needless complexity to a device set that most Americans use for all members of their home. In fact, adding user accounts and age verification here would actually make it more difficult for parents to implement home parental control systems.
4.) Every smart device from toasters to refrigerators have operating systems. While I personally don't think these devices need an OS, requiring that they all get age verification added is stupid.
5.) Every home security system has an OS. Most are not designed for separate user accounts. Requiring age verification to use a security system is a strange idea to say the least.
6.) Every car has an OS of varying complexity. Some might be able to handle an age verification system, but I for one don't like cars going online. How exactly would it benefit children to implement an age verification system into a vehicle OS?
7.) Wastewater and Drinking Water systems are often controlled using an OS called SCADA. This is a very simple OS because it needs to be. Only licensed operators are put in control of them so age verification is useless here. On the contrary, if a law says that an OS cannot be sold without age verification it technically means that the SCADA systems will be required by law to connect to the internet and add user accounts in order to be operated which would expose these systems to hacking. As someone who has experience using these systems, let me just say that if a hacker gained control over such a system it would represent a threat to public safety as a whole. This is one OS where the addition of age verification would directly endanger the lives of children.
...
And of course another concern is when the laws specifically claim to be retroactive. Should Microsoft be required to push an update for Windows 95 and DOS to implement age verification? What about old game consoles that never had an account system to begin with?
In short, these laws are overly broad - not simply because it forces adults to give up their information, but because it covers literally every piece of technology you can think of without any reason.
On the bright side, if they decide not to enforce the law against all these examples above and only target phones and personal computers then the law itself will be unenforceable because, per the equal protection clause of the constitution, a law must apply equally to be valid. If they pick and choose who they enforce the law against the law itself won't be constitutionally valid.
And if they refined the laws to be limited to only newer computers and phones? It would still present a serious risk to government computer systems that use an intranet and should not be exposed to the internet and it wouldn't work anyway. What's to stop someone from just writing a browser addon to simulate the age verification signal? If it is ever made for an open source OS, even once, that would be an easy thing to do.
Worse though is the idea of normalizing the practice of sharing personal information on the internet. When I was a child I was taught never to share things like my address with strangers on the internet, but now an entire generation of children will get used to the idea of doing just that. In the UK there are already examples of scam sites pretending to be ID verification to steal identities. And more than a billion names have already been leaked from official databases. What happens when predators obtain the name, birth date, picture, and address of children? Doesn't that put real children in danger of kidnapping?
I don't know about any of you, but I would not allow any child of mine to share that level of information on the internet. I don't care what any lawmaker says. I will protect my children with my life as any parent should do.
