The growing science of memory manipulation
The mere <i>possibility</i> of tampering with memory is indeed the most dangerous thing that could happen to humanity. Imagine not being able to believe your own memory.<p>In fact we don't have to imagine, I believe I've been subjected to "mass gaslighting" on multiple occasions recently on the internet : some piece of information I'm sure I saw on the internet suddenly completely disappears. Google + Facebook + "right to be forgotten" type of policy, make for a very dangerous power never experienced before by humanity.
