As the technology improves, it will become disruptive and enable average people to join the ranks of Hollywood actors, directors, music producers, and vocalists. The future isn't A-list celebrities and grammy winners, it's people like you and me.
Just my two cents, but acting is not as simple as wearing someone's face. If deepfakes make me look like an A-list actor, that alone will not get me a lead role in a big budget movie. I would still require acting skills.
