what happens to them after they keep going as much as they can

Suggested determinism tempts one to conclude a sentence, while ignoring to be life sentenced towards point of death. So whenever one of those whiz-kids reaches the conclusion of his efforts; the temptation to set another self imposed conclusion comes into play, which others exploit and steer.

In short...death implies as much as life can go.
