This invention of atomic bomb, certainly it requires good brain. But Bhagavad-gītā says that this genius, or this brain, intelligence, has been used . . .
(aside) Stop that.
. . . has been wrongly used.
So the materialistic class of men are undoubtedly very, very intelligent, but their intelligence is being used wrongly. Duṣkṛtinaḥ. Duṣkṛtinaḥ mūḍhāḥ. Mūḍhāḥ. Mūḍhāḥ means rascal, ass. So by their discoveries, by their materialistic activities, atheistic activities, they're simply disturbing. Simply disturbing. That's all. They do not know that, that "I am discovering these material things." If we discuss, we can prolong so many things.
Just like in India, when we were children, I saw one advertisement by the Remington typewriter machine company that, "This machine has given emancipation to the woman class, because they have found some job for typewriting." In this way they were advertising. But actually does it mean that because there are so many typewriting machine discovered, the women are emancipated? Rather, they have become dependent.
