I'm Noah, one of the founders. I also think lifelogging will be common in the future because it's becoming easier to record everything and the benefits of having that dataset are also increasing (that's where we come in)
You're correct that lying could become obsolete. It could be sort of like the changes brought on by the Information Age, where now it's pointless to argue over truths that are the public domain (since we can just look up the fact whenever we need). It would extend that to private life.
