That's just saying "we push our memory problems up the stack so our clients / users need to deal with that". The reason this works is because human users in particular have become accustomed to software being buggy and failing often.

What ?? It’s exactly the opposite of that! Memory allocation on demand frees users from having to worry about configuring memory settings, which static allocation requires except if you overallocate, which is problematic if lots of applications start doing. I absolutely don’t like the argument that memory is nearly free! Most laptops still come with around 8GB of RAM which a browser by itself can consume already … there’s really not a lot left when you also got Docker, compilers, music app, email and so on running. I have 64GB and still have to close apps sometimes because software nowadays does stupid things like overallocating. Don’t do that.
