Earlier quoted context omitted.
In modern times don't we all think that ideas are cheap: don't we all mostly regurgitate the same stock of them. Have we yet lost the open ideals of university sharing? The core of open source? The failure of the GPL is that you can't force anyone to collaborate and share if they don't really want to.
"ideas are cheap" was one of the most succesful psyops of all time, so unbelievably wrong
- E.g. an idea is "Everybody should have cheap housing! Or an even better idea, everybody should have free housing."
- Ok, how exactly in concrete terms do we actually do that? (The very expensive Execution of the idea.)
- "Uh, well, I leave that as an exercise to the reader."
Ideas are easy and execution is hard. That's what jaded people mean when they say "ideas are a dime a dozen".
