I suggest that you read some of the basic literature on
nanotechnology.  Say _Engines of Creastion_, Eric Drexler's 1986 book.
 It's online, so you don't even need to buy a copy.  Nanotech devices
are really small compared to human nerve cells.

That's also a lot of data to be pumping over a limited bandwidth and then consider everyone doing it in parallel. I think your perspective is too high level. Start at the bottom with a reasonable volume estimate per nanobot and re-run your simulation.

I did this a couple of decades ago.  So did a number of other highly
capable technical people.  Here is an example that goes into the
scale.

Search Google for "cell repair machines."  You will get about 50,000 hits.

I am very aware (as most electrical engineers are) of waste heat
management.  As long as you are sticking to normal brain speed it is
not a problem.  Where you need forced cooling is to run much faster.

If you want to run the numbers and show this is impossible, be my guest.
