It will be a generational shift. You won't get current doctors (over 40) to change their ways, ever.
My previous doctor (who was probably mid-50s) didn't use email or any kind of secure electronic messaging system. Everything had to be faxed to him.
My new doctor who is younger uses all kinds of digital tools including a voice recorder with a pre-trained text-to-speech engine that understands medical terminology and codifies the transcription based on keywords.
So it's not entirely getting away from freetext but at least it's extracting some structured data from it automatically.
Doing so could have incredible utility for sharing data across various clinics/hospitals/pharmacies/etc.
