I one person who isn't sure about that. I don't see why it wouldn't be good for us to evolve into something more advanced. Whether that's through melding with AI or advanced genetic engineering that outcome could be fantastic (assuming the transition is well managed, broadly distributed and happens through choice etc). It could lead to elimination of disease, aging, reduced ecological footprint, all kinds of benefits. And of course we've evolved before, it would be sad I think if this was the final state - I think we can do better!
