Don't even try :-)

No, seriously. There's swap. Depending on tech, using it might be
viable (NVME) or not that much (spinning rust). The sysadmin might
plug in another 2TB of RAM on request [1] (or the cloud orchestration
system might allot to you another 16G chunk).

Modern OSes usually overcommit (if you say "malloc" they say "there
you go" and fault-in page by page whenever you access them first).
