FileVault, UnBitLocker, Security, stolen encryption algorithms

Question

It's in the news, that researchers have discovered a way to extract the encryption algorithms from DRAM chips. This affects the security of FileVault.
The technical paper is here:
http://citp.princeton.edu.nyud.net/pub/coldboot.pdf
FileVault info is on page 16.
But in order to steal this info:
1- thieves must have physical access to the computer
2- one way is through a quick re-boot using an external device
This just shows that if you have sensitive information on your computer:
1- don't leave it where thieves can easily steal it (in your car, on a table in a coffee shop)
2- use a firmware password, which will hinder a boot from another device
To learn how to add a firmware password, read this article:

Bottom line: Nothing is absolutely secure.

Answer 1

This is crazy but obvious. I reviewed the Dept. Of Justice's procedure for what to do if law enforcement encounters a computer that is running but passworded. It says to not touch and call for help. So the DOJ knew about this all along.
I a called apple support, they acknowledged it but said it is unlike it will be fixed.
