This depends on the prior experience of the learner. If one is as absolute beginner to computer science, they will find deep learning to be incomprehensible. In fact, they might find it so difficult that they might give up on the idea of learning deep learning forever. So it is not advisable to try to enter the field of deep learning if one is an absolute beginner to computer science. However, if one has some prior experience in the field of computer science, artificial intelligence, mathematics, and especially statistics, they will not find deep learning to be that difficult. To be sure, it is a very advanced and complex field, but with the right amount of study, hard work, dedication, and intelligence, one can enter into it and advance considerably.
