Saving Humanity, One Chip at a Time?

At the Global Spiral , philosophy professor Mark Walker argues that transhumanism is civilization’s best bet for survival:

Transhumanism is the thesis that we can and ought to use technology to alter and improve human biology. Some likely targets for the technological makeover of human nature include making ourselves smarter, happier, longer-lived and more virtuous. The operative assumption here of course is that intelligence, moods, longevity and virtues each have deep roots in our biology. By altering biology transhumanists propose to improve human nature to the point of creating a new genus: such as posthumans. Notice that transhumanism encompasses a moral thesis. Transhumanism does not say that we will create posthumans, rather, it makes a moral claim: we ought to create posthumans. The hint of an argument based on the accrual of moral benefits is perhaps obvious from what has been said: to the extent that we value the development of intellectual, emotional and moral virtue, becoming posthuman is imperative. I won’t pursue this line of argument here directly. Rather, I want to explore the objection that transhumanism is an ill-advised experiment because it puts us at unnecessary risk. My reply will be that creating posthumans is our best bet for avoiding harm. In a nutshell, the argument is that even though creating posthumans may be a very dangerous social experiment, it is even more dangerous not to attempt it: technological advances mean that there is a high probability that a human-only future will end in extinction.

Apparently, the only way to save humanity is to get rid of it ourselves.
