AI lacks entropy and thus will never autonomously dominate the universe. Please understand that humans necessarily make irrational decisions (e.g. based on emotions and hormones and incomplete local information reasoning), because otherwise the species would not be resilient.
PoW can never be dominated by botnets because infectable computers do not have ASICs that reach even 1/1000th of the computing power the latest ASICs which are always distributed first to TPTB (i.e. the Zionists) because they control the latest technology (e.g. 14nm currently) chip fabs.
