Despite its futuristic outlook and results biohacking remains a largely unsupervised, dangerous if not illegal movement. Though the research and results produced by biohackers is ground breaking, it also breaks several ethical codes on human experimentation and endangering live of several humans.
I agree with the fact that risks outweigh advantages, but you can do things like:
- 3D Printing Body Parts
- Finding Cures
- Correcting Deformites.
The only issue is that it's illegal, unfortunately.
