Not sure why you're downvoted. It probably has to do with the implication that it might be a government or a private company that is doing the logging, but that doesn't need to be the case. We could develop a culture where we record everything around us and store the recording on our own devices, accessible only by us.
That episode was good, but the book/film The Circle I think covered this type of scenario better (even if the movie adaptation did leave a little to be desired)
I don't understand the EULA part. Are you saying that if a company sells eyeglasses with 24/7 audio and video recording to an microSD card, then that company would have an interest in adding a EULA that prevents using their own devices in a court case against someone else? Or are you saying that a hospital would have an EULA that prevents one from using any recording one might coincidentally hold of interactions with them in a court case?
The company won't be selling a 24/7 microSD recorder, it'll be selling a 24/7 cloud recorder, for the usual bullshit reasons that are ostensibly about convenience, but in reality are about securing recurring revenue. Since you won't be using a product but a service, there will be an EULA, and the company may not want their data (at this point it isn't your data anymore) trawled in random court cases.
Might not, but EULA may stipulate that breaking it will cause termination of account and deletion of your data. It would be similar to forced arbitration clause, as far as I understand them - i.e. it's not that you can't sue the company, it's that you'd better not, if you want to retain your account.
