Option 4 is not supported by the passage as it takes an extreme stance by claiming that 'digital technology is enslaving us,' which is not explicitly mentioned or implied. Option 1 suggests differences in the manner of behavior manipulation during the Cold War and the present, which is not discussed in the passage. Option 3 incorrectly attributes influencing capabilities to artificial intelligence, which the passage does not support. Thus, option 2 is the best choice and the correct answer.
