I agree it is some time away before we acquire that technology. I must point out that 100 yeas ago using horse mounted soldiers was still common, we just started building airplanes and really hadn't used them for anything useful yet, we have only had electricity for a couple hundred years, computers for a short time. Look at how fast simulations and displays are coming along. LCDs are only about 30 years old and just passed up CRT in the last 5 or 6 years. Even the telescope is only 500 years old. America is only a couple hundred years old, can you imagine showing them one of our computers in action? That was only 200 or so years ago.
There is something called Moore's Law that says that processors will double in power every 18-24 months.
The same theory roughly exists in technology in general. Given how fast we are increasing it doesn't seem out of the question that we would have matrix style technology in our lifetimes or at least before 2100.
