'Computers' are more like, industrial consciousness, though. What happens when we can grow brain cells on demand? (and support their function). Imagine upgrading yourself like you upgrade your computer. More brain. Less sleep. More hands. Armored skin. Photosynthesis.

Imagine you're a shapeshifter. You can copy any aspect of any living organism on Earth, integrate tech directly into your body, and the smartest people are coming up with new useful things to add.

Aaaand it's all banned. Enhancing your performance? Heresy!

That's assuming such research is allowed in the first place. Humans are innately repulsed by biology, by organisms. Imagine an arm with its skin ripped open to the bone, gushing blood everywhere. Imagine your guts hanging out from your belly.

And the ethical/moral rules we built over thousands of years will not allow the majority to sit by and watch some atrocious (from their POV) experiments.

So, humanity becomes the borg?

Also, taking economics to a new level, once we have got past the scarce-resource/pollution based short term thinking and it no longer is viable to have a volatile structured economy, where there is no longer a need for the profit motive. Super computing could easily take this task up of organising and fairly structuring the economy.
