“Playing God” is an interesting phrase, because it is very subjective to both religious views, and social views in terms of what humans are “allowed” to mess with and what they’re not. What makes modern genetic modification all that different from artificial selection? Humans have been genetically modifying their food sources for as long as we can remember through selective breeding, and yet few people seem to mind having cows that produce lots of milk or yummy, easy to eat bananas. If we ignore the moral implications of modifying creatures, it makes it hard to say we’re doing all that much more to modify our food sources than we have in the past.
