Michael Anissimov has listed the Top 10 Transhumanist Technologies. They are:
1. Artificial General Intelligence
2. Mind uploading
3. Megascale engineering
4. Molecular manufacturing
5. Autonomous self-replicating robotics
7. Space colonization
8. Gene therapy/RNA interference
9. Virtual reality

Neural interfacing belongs on this list — particularly as it pertains to fully immersive VR and as a precursor to mind transfer (not to mention a myriad of other applications).
I took a quick look at the Lindeman haptics paper and their proposal for feedback suits and other wearable devices meant to simulate real-world tactile and sensory stimuli.
While I am sure that this will be a technologically necessary step on the path to fully immersive VR, it won’t actually be truly immersive and believable until the development of more powerful neural interfaces.
Specifically I’m thinking of the so-called brain-jack or similar device that will drill directly into the sensory cortex. Once this has been achieved there will be no need for wearable devices that merely simulate experience. Tapping into the sensory and motor cortices will enable us to over-write unwanted incoming sensory data and replace it with the simulated experience — including touch, smell, sound, and even neurotransmitters like adrenaline.
The trick is to figure out how to do this, but I don’t think it’s beyond theoretical possibility.
