Yes, on the question on the 2 pills to choose 1 from of which 1 were to make oneself smarter and the other dumber, there actually can be very reasonable circumstances in which one may rationally prefer to choose the pill to be dumber. There is conceivable scenarios in which being dumber could lead to a timeline with better general course of events. Higher intelligence can grant access to ideas with serious dangers that otherwise were inaccessible, and at least with higher albeit at the same time insufficiently high intelligence (though not necessarily just only in that case), it may just allow making dangers real that otherwise were excluded, without possibly allowing the level of intelligence for solution or prevention insights to address specifically those dangers that may only arise from sufficient intelligence that enables such dangers to be connected with and to take hold of reality in at least some trajectories among those that it could take.
