Analyzing Assumptions in Communication Argument

Read the following argument:

In recent years, there has been a growing perception that technology is diminishing interpersonal communication skills. Proponents of this view argue that as people increasingly rely on texting and social media for communication, they lose the ability to engage in face-to-face interactions. Critics of this stance, however, argue that technology enhances communication by providing more channels for expression and connection. They suggest that rather than diminishing our skills, technology allows us to maintain relationships in ways that were not possible before.

Based on the argument, which underlying assumption must be true for the critics' viewpoint to hold?
