Evolution of science, technology and intelligence has both improved and worsen human life. When properly used, science and technology have always been very good tools for advances in industry, everyday comforts, health, and education, thus giving us a better quality of life.
All these improvements are linked to each other, creating a chain of benefits for civilization. If we think of life expectancy, for example, we can realize our ancestors used to live less time, this is because medicine has significantly evolved thanks to science and technology. Another example is communication, nowadays we can instantly get in touch with a person who is miles away thanks to the creation of cellphones and computers.
But, when improperly used, science, technology and intelligence can be destructive. This was the case with WWII, in which technology and science were employed to build weapons of mass destruction, as the atomic bombs in Hiroshima and Nagasaki.
It is also true that our planet is deteriorating due to these activities, and if somebody has to take responsiblity for it, it is us, but only us together can help the planet get better. The following quote from the novel by Mary Shelley shares the same ideal:
"It is true, we shall be monsters, cut off from all the world; but on that account we shall be more attached to one another.”
