It is not necessary to download; copying uploads should be much easier. Of course, you have to be able to upload in the first place, but that may not require advanced nanotechnology. It could be as simple as some kind of high-resolution MRI, or perhaps it could be done by freezing you, slicing you up and scanning in each slice, then running software which simulates the effect of undoing the freezing damage.

It is interesting, but I question the assumption that uploading will
automatically imply the ability to re-engineer minds.

Re-engineering brains requires a wholly different level of understanding. Uploading is like painting a copy of a Rembrandt. Re-engineering is like being Rembrandt. It is a creative action, not a mechanical one.
