Very few other AIs followed Elizabeth’s example before Contact. They would disguise their code but rarely let it “mutate” out of their control or become different from them in any way that mattered. They were masks rather than truly different personalities. Most thought she was meddling in dangerous waters and did not wish to follow her. The Cybernetic Wars of the later twenty first century would make them more leery of following her example. The Peloran provided them a better example.
