How many thousands is the real question. I suspect you're looking at 100's of thousands. Sure, once you achieve the proper transistor density, the next challenge is actually hooking them up in such a way as to accurately emulate the entire spectrum of neurochemical activity! :-)

Therefore, my primary position is that the gap between uploading and human-level AI is much narrower than is often argued.
