It states that Less Wrong is a blog devoted to refining the art of rationality. Rationality is about winning and you and me and the rest of humanity can only win if we are able to solve the problem of provably Friendly AI. What I have learnt is that one should take risks from artificial intelligence serious. And I still believe that it is the most important message Less Wrong is able to convey.

Why shouldn't the discussion of risks posed by AI be a central part of this community? If risks from artificial intelligence are the most dangerous existential risk that we face how is it not rational to inquire about it and try to improve how this risk is communicated towards outsiders?

“The primary thing when you take a sword in your hands is your intention to cut the enemy, whatever the means. Whenever you parry, hit, spring, strike or touch the enemy’s cutting sword, you must cut the enemy in the same movement. It is essential to attain this. If you think only of hitting, springing, striking or touching the enemy, you will not be able actually to cut him. More than anything, you must be thinking of carrying your movement through to cutting him.” via Twelve Virtues of Rationality

This is what I learnt and that the enemy is unfriendly AI.
