From PZ Myers:
Good news, everyone! In the future, we’ll have flying cars! And the world will be deeply multicultural, a melange of different ethnicities, all working side by side, with equal status. That’s the bright side of the science fiction universe in Netflix’s Altered Carbon.
Now the bad side. The key innovation in this story is the ability to upload and download minds. Everyone is walking around with a little disk in their neck that archives their mental state and memories continuously; some people also have a kind of brain wifi that allows them to periodically upload everything in their head to a remote backup. This means that if someone dies, they can just cut out that disk, insert it into a new body, and voila, you are revived! Unless someone shoots you in the neck, unfortunately; destroying the archive is Real Death. If you’ve got the wifi option, you can also restore from the last backup.
Wait, what’s so bad about that? It’s effective immortality! That’s where the series is most interesting, in exploring the consequences of radical new technology.
