Then, where is the jailbreak? I should have said that it was the way I feel, not that there is no actual demand for it, but, it seems that, with iOS 7 and all it's goodies, people just don't care that much anymore about messing with their devices because they are satisfied (most of them) with what they have, at least that's the way I perceive it and I include myself in that list.
You perceive it because you don't understand it. On older devices, there was a bootrom exploit. That made new nailbreaks much easier to complete. The exploit allowed jailbreakers to inject code before the os had the chance to enable security features, including the sandbox.
Apple encrypts and hides the bootrom to take this ability away. This leaves jailbreakers looking for a series of bugs to exploit to gain access to the phone. The problem with needing a group of bugs to gain access is Apple doesn't need to fix them all to break the method being used. You can see this with 6.1.3. They fixed enough such that it broke evasi0n, but not so much that the older devices couldn't still run the semi-tethered jailbreak.
As the new iOS is released, bugs get cleaned up. Code isn't completely rewritten with each new iOS. This means fixing the bug in iOS 5 often means the bug won't reappear in iOS 6 or 7 etc. This reduces the area one can find bugs. Functionality that has existed has been scoured by both apple and jailbreakers. Useful bugs are less likely to exist in these areas. That doesn't mean they can't. Look at evasi0n using the area media is transferred to as an example. It just means if there are any useful bugs, they won't likely exist in updates.
All of this means it's more difficult to jailbreak each new iOS. You can't simply claim it takes longer so therefore nobody is trying. It SHOULD take longer. As far as demand, the iOS 6 jailbreak took roughly five months. How many millions downloaded it in the first 24 hours? That's a good indication that a long time to jailbreak isn't representative of limited demand.
I'm curious what your perception is based on. It's certainly not founded on an understanding of either demand or process.
