When I am consulted on the redesign of humanity, the first thing I'll have them fix is the air conditioning. Which works somewhat ok unless there's humidity. What a clever system that is, oh omniscient Creator. Oh, and it makes people smell and want to move.
However humans can heal, evolve, and adapt to new environments and stimuli exceptionally well.
Evolution was an epic kludge. Good biology professors already teach this.
Also, if more people thought of stupidity and bad behavior as software problems, education might actually get the funding it deserves.
