First you experiment; then only you can be negative about it.
See what happened to some of the scientists:
The desire for comfort and power has created many things in the world. Science has come as a desire for both comfort and power, and it has created both. But indiscriminate use of what Science has provided is destroying humanity. So much so that Albert Einstein felt that he had done a crime against humanity. In the last days of his life, somebody asked Einstein, If you were born again, what would you like to become He said, Never a physicist again, never a scientist. Rather, i would like to become a plumber.
The very framework of science is to gain dominion over nature. That is the very terminology of science conquest of nature. We have to overpower nature and we have to destroy all mysteries of nature, and we have to find all the keys of power. But the very idea takes you away from nature, makes you antagonistic to it and becomes destructive.
The ecology of the earth has been destroyed by this power-seeking. In the outside, in the inside both the natural rhythm of life is disturbed.
The great scientific minds of this century are coming, slowly, reluctantly, to recognize that a great mistake has been done.
The very desire to be powerful is against nature. Why do you need to be powerful? You must be thinking in terms of destroying somebody. Power is needed to destroy. Power is needed to dominate. Power is needed to conquer. Science tries to penetrate nature to get more power.
