Explain why.
Unused RAM is wasted RAM. If you've got 64GB of RAM but your system never uses more than 8GB of RAM, you don't need 64GB of RAM and you're not getting any benefit from it.
On any modern os unused ram is ot simply unused. It is used for caching files and other stuff. So more ram can provide significant performance improvements for some taks even if "unused".
That doesn’t show as unused.
How does it follow then that one should use nearly all of it at all times? Sometimes I need all the memory, sometimes I don't. Sure, I don't get the benefit all the time. Same as I don't have four passengers in my car at all times.
I think the point is, if you're not carrying 4 passengers all the time, why the fuck did you buy a car when you could have bought a unicycle instead?
Silly me, I should buy a car each time I have four passengers and sell it afterwards, to avoid any wasted space.
Don't forget to sell the unicycle when you buy the car.
