There are different reasons. Some people are against a technology which isn't mature enough. I don't know about word processors, but take digital photography for example. Some people stuck with film photography even after digital became cool because it was superior in some regards (such as dynamic range). Once digital improved in every way over film, those people moved too. Another reason is job security. Why would someone support something that will leave him homeless and destitute just because the software will be superior? Personally, I think that software engineering jobs will go up while AI assisted programming is perfected (10-20 years), and afterwards there will be a huge decline (10x shrinkage) once the tools won't need people anymore.
