Should we be preserved to observe?

The following question is best contextualized with this presentation .

If we can see ourselves as a collective of 7 billion people, each corresponding to approximately 50 trillion cells; and

Assuming we can achieve eternal life;

Should we create truly better formulas than our 3.2 billion genetic codes?

Or should our old human way, among beautiful things, also slightly selfish, prohibit changing our own genetic recipe and would we require that our - perhaps eternal - own consciousness be preserved during any evolution?

Now, shorter and clearer: should we evolve anything?; or anything except to change our consciousness, our genetic code, our way of organizing 50 trillion cells and billions of individuals?

Even more summarized: should we be preserved to observe all future evolution? Even if we become relatively obsolete?

Thank you very much for your patience in listening to this question.
