We're not hiring more but we expect to do additional volume (20%) with the same number of workers over the next couple of years. Just being able to summarize PDFs is a huge time saver by itself. The efficiency gains are obvious, a significant amount of backoffice tasks can either be fully or partially automated. You'll always need a human to handle override situations, but instead of a team of five accountants processing monthly expense reports, you might only need two, a lead, and a backup in case the lead quits.
Just today apple announced an audio tagging feature to summarize audio in video clips for their video editing software. Pretty tiny incremental upgrade, but 30 seconds here and there add up to an hour a week and if you have 40 video editors on staff doing different projects, that's an entire headcount you can drop without working anyone harder. Audio summarizing might actually save more like 5-10 minutes a day depending on workflow and how close the editor is to the source content. Could be over an hour a day if the editor isn't fluent in english and is really struggling to understand what they're editing.
