New life indeed does begin at conception, but it's not fully embodied until some indefinite point in time.
*As for the usefulness of a newly conceived life or idea -- that requires time. The following anecdote may apply. Sometime in the 19th century, a delegation of government dignitaries visited Michael Faraday to view his electric motors and other inventions. One said "This is all very interesting, but of what possible use are these toys?" Faraday responded: "I cannot say what use they may be, but I can confidently predict that one day you will be able to tax them."
