For those advocating that the principles of Darwinism should rule in this complex technological world with the resultant weeding out of the unfit, I am all for it for you, so long as you hurt no one else in the process but you and yours.
However, allow the rest of us the humility to accept that we don't know everything, will not be at the top of our game every instant, will grow older with a self image that might not keep pace with the reality of our years, and cannot anticipate every contingency.
Therefore, remove all the switches, air bags or whatever safety equipment you want. I will choose to leave them on. At the end of the day, my strong suspicion is that Darwinism will prevail but, probably not in the way that you had hoped.
