Key steps for developing a cure for aging are as follows:
- Early detection of aging;
- Search and study of genes responsible for life expectancy;
- Development of the theory and model of aging;
- Creation of ageless transgenic animals.
To improve regeneration, transplant body parts and organs, grow a new body:
- Creation of a bioreactor that supports the vital activity of organs outside the body for a long time;
- Organ transplant between clones;
- Use of modified stem cells for organ regeneration;
To transfer brain functions to a computer:
- Creation of nanomechanisms and microrobots for targeted drug delivery, tumor removal, blood clot treatment;
- Nanomechanisms capable of performing the functions of individual human cells and the subsequent replacement of all human cells with them;
- Nanomechanisms that connect to neurons and transmit information to an external computer;
- Neuron replacement with nanorobots and a gradual brain function transfer to a computer.
Some experts wait on the ability to upload consciousness to a computer or cloud storage, as well as the replacement of human organs and limbs with artificial ones. With a complete body replacement, the issue of aging will disappear by itself. However, not everyone is ready to go for it. But the ethical debate around immortality is a separate issue.
The following key steps that will be required to transplant a head onto a bionic body:
- Creation of artificial analogues of internal organs;
- Life support in case of internal organ failure using external systems;
- Creation of atomic artificial organs with a long service life;
- The use of robotic surgeons for organ implantation operations.

Another possible way to achieve immortality. So far, science does not know how to bring a cryopreserved patient back to life, but experiments on freezing and thawing animals lead to more and more impressive results.
The key steps that will be required along this development are as follows:
- Improving the organ freezing technology, stem cell cocktail, growth factors and cytokines for their restoration;
- Restoring of brain sample activity;
- Screening and improvement of cryoprotectants for reversible cryofreezing of increasingly complex organisms;
- Determination of consciousness phenomenon and brain parts responsible for it, reconstruction of memories and their recording on a neural network;
- Treatment of brain damage with the help of nanorobots and restoration of the personality of a frozen person.
