(More general comment on optical media problems, alternatives and tools, and not specifically to Kurt Lang...)
Apple hasn't included an optical disk reader in any of the new Apple Mac systems for a number of years now, and which can certainly be inferred to indicate how Apple views the future of optical media.
Apple wants folks to use downloaded software and downloaded content. Not optical disks. Because optical disks have issues. And optical disk readers and optical media are on the wrong trend, billions of disks or not.
Optical disks were a wonderful idea, though with a problematic and flaky and error-prone and repair-intensive implementation; optical disk readers and polycarbonate disks. Having spent more than a little time performing low-level read and write I/O and direct control of SCSI, ATA, ATAPI and USB devices from within playback and recording tools and related device drivers I've written, optical disk readers are a mess.
As for the hardware, optical disk readers require maintenance and replacements. Having worked with these devices for many years, it's still somewhat surprising that they work as well as they do. But then audio and video are also a whole lot less sensitive to transient errors than is data storage.
What's wrong with optical recording? The optical disks scratch, and the phase-change and photosensitive substrates used in the media routinely degrade, the disks and the drives both routinely have read errors, and the optical disk reader mechanisms and optics get filled with gunk, dust, hair and whatever, and they then fail to work reliably or fail to work, and those failures require warranty service. Some of the drives are amazingly bad at basic operations, even when new, and I've seen more than a few firmware errors in brand-name optical devices. Simple media preservation and archival storage is a problem, too.
There's a whole 'nother discussion of the "fun" involved with digital rights management (DRM) and content protection lurking here, too. That adds to the complexity and cost of the implementation, and to the costs of product support.
If y'all want to use optical media — and there are most certainly good and valid reasons for still using it — then there are add-on optical disk authoring tools that can and do work with macOS. The cdrtools open-source package is one that can be used to write optical media on macOS, and there are others. The cdrtools package is available via homebrew, as well as via source code and other distribution mechanisms. The VLC package can play video, and the VLCMC package can be used to create movies and other content. VLC and VLCMC and other packages are available for macOS and other platforms. Apple offers GarageBand and iMovie and other production tools, though that's all moving away from CD and DVD recording.
If you'd like to see Apple shift their emphasis back to optical media here, then the Apple feedback web page is your best next step.
