I just said you were deadly wrong here, but rereading your post I find it somehow ambiguous. Let me comment anyway. Human classical teleportation, although possible in principle, will not be possible in our life time (except for those who will succeed in some lucky cryogenisation process). Artificial brain will first be developed with graft of genetically engineered animals neurons, through progress in harnessing the immune system and prion diseases (that will take time). Only latter will come "purely" artificial digital brain, and even this will be a matter of piece by piece progress (artificial hypocampus, artificial limbic system, .... until artificial cortex (this one will take perhaps a millenium), and pionner of immortality will have hard time for many technical but also social and ethical reasons. But where I think you are wrong is that articial brain and body, even if it needs a millenium of work to succeed with some reasonable probability, will not really help us in understanding the brain and its functioning. It just happens that, even if it is *very* difficult, the copy of a brain is almost infinitely easier that the understanding of how a brain work (even assuming some high substitution level). To be sure here comp says something rather negative: humans brains will never completely understand the human brain. It is true that the 3000 AD humans will perhaps eventually understand the basics of 2000 AD human's brain, but only true their own bigger "brain" (including self-developing machine) which will be beyond their comprehension. A little like bacteria and amoeba "learns" to reproduce themselves without any higher level understanding of what is going on. Of course if comp is correct we can understand very fundamental principles which are at the "logical origin" of the realities .... (that's what we are discussing now).
