Nonsense.
I don't get how so many otherwise smart people think we're living on a world that has the absolutely perfect climate, and that any change warmer or cooler results in disaster for mankind. The fact is a warmer climate such as that found during the Cretaceous(~ +4C) is beneficial to life.
On the other hand, just a tiny bit cooler than now and you're back in an ice age, decidedly unfriendly to life.
For the record, we are *currently* in an interglacial period of the ice age that started 2.6M years ago. When/as we exit the current ice age, it's going to warm up, period.
Franklin said essential liberty. Anarchists continually forget or ignore that. Being able to lie to the police (or hell, your parents) about how fast you were going, if your foot was on the brake or gas, etc, is not an essential liberty. If you don't like speed limits, seatbelt laws, and so on -- fight for those to be repealed.
There is about zero risk of abuse from systems like these, even if the data is broadcast openly and unprotected, live, while you're driving. For the most part, in fact, that is already happening. None of the information these devices records is information that is unavailable otherwise, except perhaps things like the seatbelts being fastened.
I regularly use keyboards from the mid 1980s, sometimes with stacked adapters to go from ATX to PS/2, and PS/2 to USB, and I'm sure that's not too unusual.
No, you don't.
Going from AT or PS/2 to USB with only an adapter is impossible. The PS/2 to USB adapters only work because modern keyboards know how to speak both protocols and can detect which kind of port they're plugged into. Old PS/2 only keyboards do not have USB controllers onboard and only work with a USB device (driver required) that provides the ps/2 port(s).
You cannot just plug an old AT or PS/2 keyboard into one of the purple PS/2 -> USB adapters and have it work, because it won't.
I can place limits on what they "can't" do, which is, "install software without my permission", the question as originally posed.
They can't do that. Full stop.
When I do give them permission to install something, I can expend the time and energy determining exactly what it is, if I so choose. Full stop.
In other words, you're still wrong on the face of it, no matter how asinine and paranoid the rabbithole you want to lead us down is, nor how empirically false your suppositions are when viewed in the context of conspiracies and game theory.
The only possible interpretation of any research whatever in the `social sciences' is: some do, some don't. -- Ernest Rutherford
