One thing I didn't realize for a long time is that it turns out that a lot of these machines have a digital stage. To cut a disk you need to pack the grooves as close as possible. But the spiral isn't fixed, it's adjusted dynamically. Quiet sections can be packed close together. That means that before cutting, the machine needs to know how much physical space it needs for the audio it's about to put on the disk. And that requires a buffer, and that's very often digital. So it turns out there's precious little vinyl out there without a digital step being involved out there.
Not that it matters anyway, since vinyl is a pretty terrible technology, but still, it's kind of funny.
“Look ahead” to determine optimal groove spacing doesn’t have to be done digitally, even though digital makes this much simpler.
I’d guess that musicians and producers using an all-analogue recording / mixing / mastering process where they have zero digital stages to the master tape are very few and far between nowadays. Kevin Shields for one, but he likely has other options for his analogue master disk cutting, and only needs to attend disc cutting once or twice a decade/century.
A transparent digital stage for the master isn’t going to make a huge amount of difference really, and the limited bandwidth of vinyl compared to digital means that the vinyl master has to be squashed and limited regardless.
Dam right. It’s a medium that a reasonably intelligent individual from any time in future/past history could intuitively understand. Let’s not forget that NASA chose a record to store the digital images it sent with Voyager on precisely that assumption.

If they are using well refined conversion paths with enough bit depth, that buffer stage will be completely invisible even at the waveform level.
As a person who likes, buys and listens vinyl, I don't care how it's processed to that stage as long as it sounds fine. Note that I don't buy vinyl because of the "sound quality per se", but for the experience of listening it. I like to make time to listen my favorite albums properly, and vinyl is a part of that for some albums. I'm equally fine with audio from a CD or a well encoded lossy codec. I can distinguish between lossy and lossless encoding of the same album, but I don't always have time to appreciate that.
So, some references (This guy has enough knowledge to write his own DSP plugins):

70 years ago Miles Davis vibrates some air with his horn, which is translated into electricity by a microphone, which is translated through magnetic tape and eventually back into electricity and then back into vibrations on a disk. 70 years later I can take that disk and turn its vibrations back into electricity that moves the air on my living room. No encoding, no decoding, just air and electricity that my ancestors will be able to replay until the end of time.
That's as close to magic as anything humanity has ever come up with in my opinion.
