Both authors believe that traditional techniques hold value that can appeal to people in the modern era. Author A believes this value lies in preserving the original form and its unique warmth and beauty. Author B believes this value can be realized by adapting the techniques to modern products. Despite their different approaches to preservation and innovation, the fundamental belief that traditional techniques possess inherent, enduring value is common to both. Option 2 is a point A emphasizes but B is trying to overcome, so it's not a shared view. Option 3 is B's viewpoint, but not A's, as A insists on preserving the traditional methods. Option 4 is also B's stance, directly contradicting A's philosophy of faithfully protecting tradition.
