Just as important as the technology will be the legal framework that applies. Myself, I like the Bill of Rights and I want to see data storage be treated as an extension of my memory with all rights that apply to my testimony extended to the digital media that is protected by a key that is in my memory. I know, naive idealism is dumb.

Just say it was the cat, who'll ever know you just committed perjury? Besides, my cat just tacitly agrees with everything I say.

To say that DNA sequencing is good technology because it helps solve crimes may be true but there is a fundamental flaw in the logic used to support their Big Brother style plan: they've already caught their suspect without DNA. They should only be allowed to take a DNA sample of a suspect if they are holding DNA evidence that could link someone to the crime. Apart from that, gathering DNA that is unrelated to a specific crime and conducting random searches trying to match to crimes where there is no suspect could be an illegal search. Sure some bad guys will get away but giving too much leeway to authorities is the greater of two evils.

Actually, there is already a way of hiding the apparent lack of magnetic monopoles in Maxwell's equations. You can write them in a symmetric form and everything works just fine without the distinction between electric and magnetic monopoles. The lack of monopoles implies that the ratio of magnetic "charge" to electric charge is a constant. The observation of a free monopole could be sorta cool.

I saw it years ago on MacGuyver.
