Another anecdote from someone who is also in the music production scene - 32GB tended to be the "sweet spot" in my personal case for the longest time, but I'm finding myself hitting the limits more and more as I continue to add more orchestral tracks which span well over 100 tracks total in my workflows.
I'm finding I need to commit and print a lot of these. Logic's little checker in the upper right showing RAM, Disk IO, CPU, etc also show that it is getting close to memory limits on certain instruments with many layers.
So as someone who would be willing to dump $4k into a laptop where its main workload is only audio production, I would feel much safer going with 64GB knowing there's no real upgrade if I were to go with the 32GB model outside of buying a totally new machine.
Edit: And yes, there is does show the typical "fear of committing" issue that plagues all of us people making music. It's more of a "nice to have" than a necessity, but I would still consider it a wise investment. At least in my eyes. Everyone's workflow varies and others have different opinions on the matter.
I know the main reason why the Mac Pro has options for LRDIMMs for terabytes of RAM is specifically for audio production, where people are basically using their system memory as cache for their entire instrument library.
I have to wonder how Apple plans to replace the Mac Pro - the whole benefit of M1 is that gluing the memory to the chip (in a user-hostile way) provides significant performance benefits; but I don't see Apple actually engineering a 1TB+ RAM SKU or an Apple Silicon machine with socketed DRAM channels anytime soon.
I think we'd probably see apple use the fast and slow ram method that old computers used back in the 90's.
16-32GB of RAM on the SOC, with DRAM sockets for usage past the built in amount.
Though by the time we see an ARM MacPro they might move to stacked DRAM on the SOC. But i'd really think two tier memory system would be apple's method of choice.
I'd also expect a dual SOC setup.
So I don't expect to see that anytime soon.
I'd love to get my hands on a Mac Mini with the M1 Max.
I went for 64GB. I have one game where 32GB is on the ragged edge - so for the difference it just wasn't worth haggling over. Plus it doubled the memory bandwidth - nice bonus.
And unused RAM isn't wasted - the system will use it for caching. Frankly I see memory as one of the cheapest performance variables you can tweak in any system.
