Personally I see a lot of potential in cybernetics for humanity.
As it stands our bodies aren't terribly amazing for space travel and each day we only seem to uncover more issues on that front.
At the same time i see great dangers. Obviously the potential for outright slavery is high.
If we're not careful we could easily find ourselves in a scenario where people get augmented for work and find that the value of said augs is fickle at best. But due to proprietary technology they're stuck with now useless parts.
So pushing for open formats and technology on this front is deffo a way to go. Warning the public in general about the dangers of proprietary cybernetics and how they'll never be able to upgrade or use a competitors components.
People will still fall for it. But with time said people will suffer for it and while we won't save many early on we'll start saving more each generation.
I think probably the biggest thing is to try and discourage reactionary modification. As in getting cybernetics in response to something such as an offer of employment or current trends.
The alternative is genetic engineering. We could work to make humans innately superior. Addressing flaws and so on.
As it stands though genetic engineering is likely to come long after cybernetics. I reckon you'll see full body prosthetics long before you see genetic engineering becoming widespread in humans with positive results.
But that brings us to another issue. In the wrong hands genetic engineering is just as bad if not worse than cybernetics in the wrong hands.
So yeah we need to keep this shit out of der judens hands. Set the terms ourselves and ensure the ability of the people to make their own decisions in this regard.
