Frictional unemployment is a good way to handwave away the discovery, or not, of new jobs. You just wiped out that whole -type- of job, replaced it with (much lower employment) error checking.
If you assume that for a portion of the people in the transcribing job, that the transcribing job was the best marginal fit, then some of them don't re-enter the job market. Others have to take a worse job. If they could have been in a better job, they likely would have been. So their employment has gotten worse. May be quality, may be compensation, may be available time. Something's worse for them.
