I also heard that sometimes you need to physically carry CDs to doctor's office. I suppose getting pictures of your MRI scans via Web is a good middle ground.
It just really irked me that people got CDs instead of being fully digital. The last time I used a CD (besides my PS4) was 10+ years ago. I don't even have a CD player anymore. I'm sure Gen Alpha will look at CDs the way I look at floppy disks.
