Planes don't fly like birds. We have ornithopter which are crude imitations of bird flight. Very crude. Similarly our AI are a very crude imitations of the real thing and I believe will continue to be for some significant time. At least a few hundred years for a somewhat plausible imitation of an intelligent machine. I believe extinction of the race within the next 10,000 years is incredibly likely. I also don't think the intelligent machines that we build will last very long because they will be difficult and expensive to build and because of the incredibly small size of their tech, say 1 nanometer or less, will be prone to various kinds of failure and also require rare materials that are in limited supply and can't be recycled so they are difficult to obtain for both us and for the AI to maintain its own supply chain without us. So our bots will go extinct soon after us.

Consciousness transfer is probably 10s of thousands if not millions of years away.
