Other possibilities using the techniques of synthetic biology are not so certain. AMny fear that such knowledge and capabilities will lead to the eventual genetic altering of mankind, and perhaps even the purposeful creation of an alternative being that will supplant humanity with a new race of "persons," possibly humanoid but in reality synthetically designed to be better than humans in their interactions with the world, use of resources, et cetera (Oxford 2008). While this is a future that is heralded by some as the next logical step in our own evolution -- why let it occur haphazardly and slowly if it can be accomplished through careful planning and design? -- others see this stance as full of dangerous hubris, and an insistence that humanity knows best despite the fact that it has shown itself time and time again willing to grossly misuse available technologies to detrimental ends. The synthetic creation of other "persons" and even the alteration of existing human beings is fraught with many ethical considerations, not the least of which is the fact that we simply don't know what we don't know -- the effects of such synthesis are likely to be surprising and unexpected, despite the best of intentions and the most careful planning.

This is no surprise to you, of course; you played your hand very close to your chest with evolution for years, fearing the effects it would have on society and on science. History has definitely shown that caution is prudent, and the way you lived your life is excellent evidence of this as well. Before folks go rushing off armed with your ideas, they ought to take a moment to get to know you, as well.

Sincerely,
