Taking another stride forward, your brain implant in 2020 will, then, be faster than an i7, have 16GB of RAM, 2TB of storage, and be able to re-render the whole of Toy Story 3 in 10 minutes. Somehow, that doesn't even sound surprising to me anymore.
What numbers did you base yourself on for the Toy Story claim? I'm curious.
[Update: If it helps rescue me, I found a page about the difference between rendering TS1 and TS3 in their respective times:

It turns out the original Toy Story took an hour per frame to render, whereas Toy Story 3 can render in real-time (or 24fps, at least.) Given that's probably on a server farm, my claim is still hyperbole, unless you expect cloud processing to be mainstream on all devices by then ;-)]
