We'd need to keep our operating systems simple, to avoid taking space away from the data we'd wish to store.
Vector monitors are attractive that way, since it'd take less software to render abstract data to those displays. By rearranging hardware rather than adding more of it.
Speakers are even simpler to build, without needing more software abstractions. Though it does require a multiplier.
Making the OS a programming language interpreter is a proven strategy for simple OSs.
