I really like efficient code, and that includes memory and storage-efficiency.
Luanti, where i run a server rn, uses less than 1 GB of storage space for a huge world, and i think the whole program code for all of mineclonia+the core luanti engine only uses sth like 30 MB. it's really storage-efficient.
I have the suspicion it's not even about shareholder profits, it's use dumb/useless metrics of success.
It's the equivalent of measuring a programmer's productive output in number of lines of code written. It leads to code like this:
Something similar happens with storage space: It is wasted unnecessarily because media designers are paid for "high definition" assets.
