That there's an upward trend isn't what matters:  what matters is the

How much of the upward trend the product can cover will limit its
lifespan.

 
Of course.  So then, what is that trend?
 
As I've already said, my observation is that its ~4GB/decade or less.
 
Mainstream users often replace their PCs more frequently, so the
practice of "upgrade at replacement" has replaced component upgrades.
 
For example:
 
Notebook:
2017-present:  Started with 8GB, hasn't changed.
(FYI: likely to replace this machine in 2025).
 
Power desktop:
2012-2022:  Started with 24GB, never changed.
2022-present:  32GB
 
Post your own hardware history for the past decade.

"The plural of 'anecdote' is not 'data'."

I believe I've had two machines this past decade.  The
old one I'd built, had 64GB iirc.  Current one has 258G.

$ lsmem
RANGE                                  SIZE  STATE REMOVABLE BLOCK
0x0000000000000000-0x000000407fffffff  258G online       yes 0-128

Memory block size:         2G
Total online memory:     258G
Total offline memory:      0B

RAM is cheap and handy to have around.  By default, Linux
Mint splits the RAM in two, half of it ramdisk for various shared
memory operations.  It's owned by root, but world-writable with
the sticky-bit set.  So one can:

_[/dev/shm]_(vallor@lm)🐧_
$ time -p tar -xf ~/OS/linux-6.11.8.tar.xz
real 8.45
user 8.16
sys 4.02
_[/dev/shm]_(vallor@lm)🐧_
$ ls -ld linux-6.11.8
drwxrwxr-x 26 vallor vallor 820 Nov 14 04:21 linux-6.11.8

 ...so you're most of the way to building Linux on your hotrod.

_[/dev/shm]_(vallor@lm)🐧_
$ df -h .
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           126G  2.5G  124G   2% /dev/shm
