1. The slow pace of Robot's development overcoming physical challenges compared to fast pace of Artificial Intelligence development once again proves the intelligent design of nature: our (Human's) physical ability is much limited now compared to the young age of our race, but our mental ability (intelligence) is much superior compared to that of our young age (with or without our tools e.g. AI). Evolution eventually has chosen making mental ability e.g. intelligence to be superior than physical ability since this choice gives the best chance of survival. Hence Human reigns over physically superior animals.
