Here's the breakdown:
Metal Prosthetics in the Real World:
* Yes, metal is used in prosthetics. But it's not like the intricate, near-human, magically animated limbs in FMA. Instead, metals like titanium and stainless steel are used for their strength and durability.
* Current prosthetics are primarily focused on function. They are designed to provide mobility and support, not to replicate the appearance of the original limb.
* Advanced prosthetics use sensors and electronics. These allow for more intuitive control and can even provide feedback on pressure and movement.
* The "Automail" of FMA is still in the realm of science fiction. We don't have the technology to create self-repairing or alchemy-powered prosthetics.
Why Real World Prosthetics Are Different:
* Limitations of materials and technology: Current materials and fabrication methods can't achieve the complex, self-sustaining systems seen in FMA.
* Ethical considerations: While FMA's alchemy is fictional, it raises real-world concerns about the ethical implications of advanced prosthetics, particularly in terms of augmentation and human enhancement.
The Future of Prosthetics:
* Research is ongoing: Scientists are working on developing biocompatible materials and sophisticated interfaces for prosthetics.
* 3D printing is revolutionizing the field: It allows for custom-made prosthetics that are lighter and more adaptable.
* Artificial intelligence and machine learning hold promise: They could enable more intuitive control and even help prosthetics adapt to changing environments.
In Conclusion:
While we can't replicate the fantastical prosthetics of Full Metal Alchemist just yet, the real world of prosthetics is advancing rapidly. The future holds exciting possibilities for making these devices more sophisticated, functional, and even aesthetically pleasing.
