Rationality Quotes from people associated with LessWrong

The other rationality quotes thread operates under the rule:

Do not quote from Less Wrong itself, Overcoming Bias, or HPMoR.

Lately it seems that every MIRI or CFAR employee is excempt from being quoted.

As there are still interesting quotes that happen on LessWrong, Overcoming Bias, HPMoR and MIRI/​CFAR employee in general, I think it makes sense to open this thread to provide a place for those quotes.
