This is just a software limitation, you can't turn the option on and trust that they can't work around it next month. As the article says, RAM encryption is obfuscation more than really doing anything. It would be rather impressive if you could encrypt the key necessary to decrypt your RAM yet continue to use the computer. That isn't to say RAM encryption doesn't have other benefits, but if your computer is unlocked and unattended, then yeah someone is going to be able to dump those keys one way or another especially if the system isn't tamper-safe (like a smart card aims to be).
