In this case, the user is deciding that they choose what progress is. I am saying, that people who use the tool and value the utility of it decide what is progress. If people listen to the podcast, or use doctors in the phone because it provides them any value, it will be a change and a perceived progress for them.

If the generated podcasts did not bring any value to the users, such as validation, or engagement, they would not use them, and there would be no change.
