That is the problem, it's a Pandoras box and once it begins it will be very hard to stop it...however, I think that it is an inevitability, just the same as machine intelligence, and either which way you frame it, Homo Sapiens becomes out-dated.
As the great philosopher David Bowie put it:
Look at your children
See their faces in golden rays
Don't kid yourself they belong to you
They're the start of a coming race
The earth is a bitch
We've finished our news
Homo Sapiens have outgrown their use
2:0 onwards
