And the max storage in pre-built computers has stagnated at 2010 levels (~1TB). This was first due to the switch to the much more expensive and much faster charge trap flash. In the 2020s it finally started to approach 2010 sizes in pre-builts but then the corporate finance wars re: fab capacity happened.

I have always felt insulted that most laptops even offer a low 4 GB of RAM I rather take 16 GB in previous gen memory

My several years old laptop has 128GB of RAM, is that not enough? I admit that it's a pretty heavy one.

for the most part, unless soldered down, it has been hard to find higher than dual channel (maybe quad for a massive odm gaming laptop). each stick and platform having set maximum memory capacity has put a glass ceiling for those machines.

doesn't matter anyway when things are not reasonably priced. i am stuck at the same memory capacity in my personal system for the better part of two decades, partially due to the above and the current pricing today.
