I’m not sure if this is surprising to me or not. I can imagine the following scenario:
Bob: “I just implemented chdir. It’s really simple, just a couple lines of code.”
Alice: “Hmm, if we add an rdir field, we can easily continue to run V6 an V7 programs, since we can copy the old directory hierarchy. Better make that super user only, as there’s probably some caveats we’re not thinking about.”
Mallory: “You know, I can just do cd .. to escape this, but if you prevented me from doing that, we could make network daemons a bit more secure since we can ensure there’s no chance of my friends grabbing /etc/passwd due to a bug.”
It’s a pretty valid evolution of an idea. You have a seed idea, which is typically simple. SMS messaging, serving Hypertext, and suddenly new ideas stem. “What if the Hypertext was generated on the fly, and used to, say, display the inventory of my store in realtime?” “What if we used SMS as a mechanism to notify ALL of your friends at once where you are, or what you’re doing?” I’m sure there’s a phrase for this that better sums it all up.
