Those following this path of restoration and affirmation of life's spiritual foundation will seek to minimize human perturbation of the natural life support systems that have evolved over millions of years. There is ample opportunity to create long-lasting, stable positions that provide family livelihoods and meaningful and rewarding work to everybody if this path is followed in preference over the other one. This path is one of humility, appreciation, thankfulness, concern for all, caution, patience, balance, respectful awe of the Creative Power that far surpasses human capabilities. And to you, too, I bet. Nobody can keep track of everything that's impinging upon their life and livelihood.
Living gets more and more frantic, more and more conditional and uncertain.
In the evolutionary timescale, it will still be instantaneous. Taking 100 years will assure ample time for relaxed consideration of the possible consequences of their introduction, and whether there is really any point to widespread use of this new, manufactured life form in the first place. The new organism's behavior under widely varied conditions can be observed and evaluated. With no compulsion to hurry in lunging dog fashion, stress within all parties will be reduced not increased. Life will be more enjoyable and satisfying.
