Is the Internet making us indifferent?

[Thorne]

It's not just a theory. Our invention of medicine, hospitals and aid for the handicapped has hampered selective breeding quite a bit. I'm not sure what you mean with cannon and factory fodder? Our brains have probably not changed much since 30 000 years. Evolution doesn't work that fast. Sure, there's been adaptions. But nothing measurable. The genetic errors that are increasing is the errors that prevent an unaided human to survive.

Not sure I like the term "selective breeding." It brings up thoughts of the Nazi effort to create a super race. But if you mean "natural selection" then I have to agree with you. People who, even 100 years ago, would have died in infancy or childhood, are living at least long enough to procreate, tending to infuse defective genes into the pool. We therefore have more and more people dependent upon medical intervention for their survival, placing an increasing burden upon the medical resources, causing an increase in cost.

Simply put, I believe the wrong sort of people are breeding out of proportion, largely due to the need for cannon & factory fodder.

This really scares me! What do you consider "the wrong sort of people?" People who are not like you? And for most of the world, cannon fodder is a thing of the past. Modern warfare requires much less brawn and a lot more brain. The same with "factory fodder." Routine drudgery is being taken over by automation, requiring fewer people to sit at a machine all day doing one simple task. Of course, then you have more people sitting around their homes watching the idiot box all day, unable to find simple jobs which won't tax their minds, putting a burden on the welfare system.
