"DDR5 will allow for individual memory chips up to 64Gbit in density, which is 4x higher than DDR4’s 16Gbit density maximum."
Apple could offer a lower density memory similar to DDR4 on the entry models to keep the price down and use higher density for the 32GB options. 64GB may not be available until later but it depends on how they designed it. They might be able to stack the 32GB memory. For higher than 64GB, they could have an external memory system in addition to the on-chip memory in the iMac and Mac Pro but 64GB would probably be enough for the iMac for now.
Now if Apple could only make a stable, drama free OS for it's Macs....
They absolutely do. My Macs have been stable and drama free for well over a decade. Your drama problems may be PEBCAK.
Bug Sur is the first OS which put my Mac in a coma. I have used Macs since the very first Power Mac early 90's. Got another theory? Keep drinking the Apple cool aid and blaming others for bad software.
