I would venture to say that most of the world isn't using computers with 32GB RAM...
399 laptops with 4GB of RAM: https://www.pcgarage.ro/notebook-laptop/filtre/memorie-capac...
548 laptops with 8GB of RAM: https://www.pcgarage.ro/notebook-laptop/filtre/memorie-capac...
Less than 200 laptops, in total, with 16GB RAM or more. So probably less than 20% of the laptops on sale have that much memory, in 2018.
The "real" world is quite different to what us folks in IT see in our corner of the world.
* Literally every current MacBook except the 15" MBP
* iMacs unless you choose to upgrade the RAM
* My local PC retailers website has 34 models with 4GB of RAM, 84 with 8GB and 28 with 16GB. The cheapest 16gb laptop there is €1100. They also sell 3 Chromebooks and 1 windows 10 device with 2GB of RAM..
