I doubt that’d work. At first anyway.
The way I’ve been viewing the Primer as of late is that it sets up a sort of “virtual machine” in the brain. Has instructions to set up the brain equivalent of assembly language opcodes.
Then the scripts from the actual sub title are more like assembly language that tell that installed VM what to do.
With an idea like that, I bet you could probably listen to the primer enough to get it set up and then be able to do just the sub title script part after.
EDIT: I’m a geek so tend to waste a lot of time thinking of stuff like this. Basically just talking out my ass haha.
