Future of bioengineering & human capabilities

Bioengineering has led humanity quite far, combining elements of engineering & biology. Bioengineering also has its dark side, because it is obvious that people have to torture animals to get a working result on humans. Even other that that, German Nazi scientists & Japanese scientists of WWII period did torture humans because they can, too, but even knowing their atrocities, without approving them, we cannot deny that these actions did lead us forward in a scientific way, making some progress.

Without testing on animals, many things, such as organ transplantation, insulin & diabetes treatment, penicillin, asthma treatment, neurology would have not likely been available to humanity.

Biomedical engineers have developed a number of life-enhancing and life-saving technologies. These include:

Prosthetics, such as dentures and artificial limb replacements.

Surgical devices and systems, such as robotic and laser surgery.

Systems to monitor vital signs and blood chemistry.

Implanted devices, such as insulin pumps, pacemakers and artificial organs.

Imaging methods, such as ultrasound, X-rays, particle beams and magnetic resonance.

Diagnostics, such as lab-on-a-chip and expert systems.

Therapeutic equipment and devices, such as kidney dialysis and transcutaneous electrical nerve stimulation (TENS).

Radiation therapy using particle beams and X-rays.

Physical therapy devices, such as exercise equipment and wearable tech.

The practice of biomedical engineering has a long history. One of the earliest examples is a wood and leather prosthetic toe found on a 3,000-year-old Egyptian mummy. Before that, even simple crutches and walking sticks were a form of engineered assistive devices, and the first person to fashion a splint for a broken bone could be considered to have been an early biomedical engineer.

Humanity actually seems to have a bright future on this sphere, because with efforts of biologists, we are advancing rapidly.

For example, recently, Japanese scientists had created drug that regenerates teeth: https://www.good.is/japanese-researchers-invent-game-changing-drug-that-could-help-grow-back-teeth-ex1#:~:text=Thankfully%20a%20group%20of%20Japanese,the%20research%20results%20of%20Dr.

It is well-known that some lizards can regenerate their body parts. Doing more research on that, we can understand it in the future to have it available for ourselves. Efforts on replacing burnt body parts are also being done. Understanding that, it will be possible to get limbs back, it would also increase longevity significantly.
