Are people of the opinion that Apple shouldn't raise the base level to 16Gb (with the same current pricing of the 8Gb), of the opinion that it should stay that way forever, or at least the foreseeable future? How long until starting at 16Gb would be appropriate?
Just for history, 8Gb has been the base level RAM in the Macbook Air since 2017, so for about 6 years. The base level RAM was 4Gb for 5 years, and was 2Gb for 4 years. (Near as I can tell, 2008 was when starting RAM was raised from 1Gb to 2Gb on Macbooks).
Here's the full timeline of MacBook Air base model RAM.
2008 (original) -> 2Gb
2012 -> 4Gb
2017 -> 8Gb
So, take it for what its worth that a product that's been around for 15 years has seen 2 bumps in base-level RAM.
The argument that Apple would have to raise the price if they upped the base to 16Gb doesn't match history. Unless I missed something when researching, the starting price of the base 13" MacBook Air model went DOWN in price when they upped the base RAM from 2Gb to 4Gb in 2012. When they went from 4Gb to 8Gb in 2017, the price remained $999.
Sorry but your analytical
viewpoint is fatally flawed.
RAM utility is totally non-linear for lots of reasons, primarily due to OS/apps memory management and usage, which are
constantly evolving. We have watched that evolution, starting with sneakernet diskette changing 128k, through Photoshop sequestering its own RAM with
scratch disks, to HDD swap, to faster SSD swap, to far faster Apple-specific SSD swap, to Apple's Unified Memory Architecture (UMA). My guess is that
UMA is disrupting future RAM utilization in a big way right now.
Edit: In answer to the question of your first paragraph: Only Apple can know how the combo of memory management/OS/SSD speeds/
UMA/RAM costs and users' needs all interact to determine what the minimum RAM level should be. What we do know is that it is non-linear and constantly changing.
E.g. My workflow today is running under 16 GB of RAM that is constantly maxed out, but Monterey still lets me get work done (albeit with some hiccups and slowdowns); a decade ago the OS would simply have crashed or slowed intolerably. So yes, Apple's memory management may allow running under 8 GB RAM for a very long time for less demanding users. Apple probably will not raise from 8 until the always-falling cost of RAM makes it internally cost-effective to do so. That might be tomorrow or it might be 2025; UMA is a new paradigm.
Note that $400 to add +32 GB RAM of Apple's superfast on-chip UMA feels like a
huge bargain to those of us who paid
$400 for 2 MB of third-party RAM in the past. That is why I included 96 GB RAM instead of 64 in yesterday's MBP purchase order. My expectation is that UMA will cause OS/apps evolution to take advantage of that RAM by midway in the lifecycle of the new MBP - - if not sooner.
