The single use part is inconvenient, but the killer is the key exchange. You need to have a new 'pad' for each person you need to communicate with, and you need to get it to them in the first place, without it being compromised. And you need very high quality randomness, which is surprisingly difficult to generate.
Actually, I'm just not sure the Culture could actually ever work - if you look at it, the culture is more like a benevolent dictatorship, run by the Minds. Humans are pretty much all irrelevant. At best pets in a zoo, given the illusion of freedom by permitting them to take on tasks drones would take care of anyway.
Citizens wage as a social policy is gaining some traction. It seems counter intuitive, but just handing out money to everyone actually just works. There are very few people who are 'true scroungers' content to do nothing at all. Most of these are gaming the benefit system or taking to a life of crime as their 'profession' anyway. But if you give everyone the basic amount they need to live, you don't change much anyway. After all, that's sort of the point of tax brackets anyway.
Some people go and earn more, others do socially useful things like care for ailing relatives, or voluntary work.
And it still doesn't cost that much when you compare it to the overhead of a complex social security system.
When you've got data from smartphones, the satellite imagery is largely irrelevant. You've already got a solid identification, location fix, and for bonus points - local audio and video. A photo of your hat won't make much difference.
Especially now a UAV capable of carrying some quite high quality camera hardware is actually pretty cheap. I've been admiring the 8 rotor which can take a decent SLR on a gimbal. It's not exactly cheap by 'home user' standards, but it's a comparable price to the camera it's carrying. Compare to the price of a satellite and launch though... there's really no contest.
Most biometrics do stop working when you die. Retinal prints change if there's no blood flow - the 'eyeball-on-a-pencil' just doesn't work. Other methods... well, generally you can detect a pulse, and the change in pattern from the blood pressure is more secure anyway. (Even before you decide you don't want to let zombies^Wresidual human resources in.)
We're used to using SSL from client to server. But it works both ways around. You can use client side SSL certificates to authenticate. Client side SSL certificates that you can lock down with a decent passphrase, SSLVerifyClient
Not as hard to implement as some of the pipe dreams out there. Of course, it does require a degree of tech savvy on the part of users - and more importantly, enforcing it's use, to avoid laziness bypassing.
Then your challenge becomes certificate transport - you'll need a way to carry around your cert, or somehow get hold of it when you need it, which is easier said than done. The real advantage of passwords is their portability. Biometrics have a similar advantage, but as already noted - are a bit harder to revoke/change.
I have wondered, give that drones are getting quite cheap - how much would a true 'peer to peer' network node cost? One that forms a mesh across a city, and finds 'downlinks' in the form of open access Wi-Fi to create a... well, routed, self healing network. True routing protocol discovery and all.
I've espoused the doctrine of proactive laziness since I started sysadminnning. I figure I'm doing my very best work when there's nothing that I need to be doing, and I can be spending my time fiddling with the next thing.
That means applying appropriate automation and scripting. (Don't overdo it - not all scripts need to be gold plated).
Decent documentation. (Which is easier: explaining or fixing a problem, or saying 'RTFM' and waving a hand dismissively - if TFM is up to scratch, they won't come back and bother you)
Tackle tasks that'll become a pain, before they're a pain.
The combination of these means I've had a fairly easy and productive live in 'systems admin', because I've never had a need to diddle with spreadsheets to look like I'm working.
Lots of people 'play spreadsheets' all day, which is working really inefficiently. Some companies prefer this, because they operate on billable hours in the first place. You being efficient costs them money. Some companies know better, and will value your skills. You should go and work for those. Getting laid off sucks a bit, but it's far from the worst thing that'll ever happen to you.
If you pull out the all the stops occasionally, you're a hero. If you do it routinely, you're taken for granted. It's hard enough to measure 'productivity' in IT anyway. Far better to automate your job, and 'pay yourself' to support it on an ongoing basis.
Scripts are generally more accessible, but that's about it when it comes to comparison with other languages. That means you get some pretty bad scripts, but... well, there's no real reason to not use decent coding practice. The core one being 'get everyone involved a working knowledge of the language'.
One boeing aircraft may look much like another at 10km distance. And boeing make military aircraft as well as civilian. *shrug*. It _could_ all just be a horrific accident.

Just make sure you encrypt the backup... oh wait...

I think you then get into an interesting conversation about how easy you want to make it for a clever criminal to avoid getting caught.

Politicians aren't 'in charge' anyway. They're representatives of their constituency. Or should be.
What makes you think those are fakes?
Watch out for people wearing google glass or carrying a smartphone too. Actually, that's probably by far the bigger threat here.

Secure sites will get upset if you drive a car through them. Cats they're much less likely to make a fuss about...

I've never had this response. Most employers like the concept of an employee who can do the work of several.
So do it in Perl - it'll be good enough to make your life easy, and inscrutable enough that anyone trying to 'automate you' will recoil in horror.

Not that you'll care, if you're the person who's already moved on :).
There are plenty of things that persist despite not being scientifically valid. Like homeopathy, for example.
