Trump is entirely unacquainted with either science or scientific thought, and to be fair, the same applies to many world leaders, who view science merely as a tool for military weapons or economic gain, if they think of it at all. Elevating the bullies of the world into positions of power has had a deleterious effect upon our future prospects. Putin, Trump, Xi--and then the nitwits of Iran, North Korea, and really most all of Africa. I think there is a great case to be made for pessimism over the future of H. Sapiens, given that many of these leaders have vast arsenals, including biological, chemical and/or nuclear weapons at their disposal. Probability will run its course, and there is a distinct probability one of these nitwits will miscalculate at some point in time and set off a most regrettable chain of events.
Therefore, what is an ethical person with sense to do? Enjoy life, I suppose, and try not to dwell upon the coming end of humanity, and try to secure little pockets of knowledge and culture into safe havens that can endure, perhaps, the coming nuclear/biological/chemical Apocalypse, when vast numbers of the human race will perish in suffering and death, slowly or mercifully quickly. It is well to stockpile cans of pinto beans and dried milk, as I know many folks that do, but also stockpile books and data, because much learning could be lost when the Internet is no more, and libraries have burned to the ground.
