What this video covers
The sunk cost fallacy is letting money, time or effort you have already spent - and cannot get back - keep you committed to something that is no longer worth it. The only sound question is what the next step is worth; the fallacy answers a different one - what you would be "wasting" by stopping.
The £80 and six hours were gone the moment you spent them, whichever button you press. The only real choice left is whether the next four hours are worth it - and the instant the demo stops reminding you what you have sunk, that answer gets a great deal clearer.
