Answer:
to provide evidence that the age of discovery is concluding
Explanation:
The author’s purpose for including this statement of the above excerpts from Choreographers of Matter, Life, and Intelligence is to provide evidence that the age of discovery is concluding.
Choreographers of Matter, Life, and Intelligence was written by a physicist and author Michio Kaku who critically examines the great scientific revolutions that have dramatically remodeled the twentieth century–the quantum mechanics, biogenetics, and artificial intelligence–and shows how they will metamorphose and alter science and the way humans live.
What actually makes Michio Kaku’s vision of the science of the future so captivating and so distinct from just mere forecasts of most thinkers is that it is derived from a groundbreaking research taking place in labs today, as well as the harmony or the like-mindedness of over 150 of Kaku’s scientific colleagues. Science, for all its magnificent change, progressed slowly; we can correctively predict, asserts Kaku, what exactly the direction of science will be in the future based on the tracks that are being forged in the present.
