I think our issue is much more banal: we are very slow talkers and our effective communication bandwidth is measured in bauds. Anything that could bridge this airgap would fucking explode in intelligence.

Yes, that's one aspect.

Our reading speed is not limited by our talking speed, and can be a bit faster.

And that's even more true, if you go beyond words: seeing someone do something can be a lot faster way to learn than just reading about it.

But even there, the IO speed is severely limited, and you can only transmit very specific kinds of information.
