Re: Huge foreheads, flat faces and saucer-like eyes
A hundred thousand years is a long time, but I don't think there will be much change in the human form, usnless it's brought about deliberately.
Of course, humans are incredibly unpredictable, even as a nation state, so you can't confidently say what will happen.
But if things go on as they are now, there is no real pressure on particular phenotypes.
There might be some dumbing down, as the better educated and more intelligent have smaller families.
I don't see bigger brains being likely to evolve, although it is a possibility that they might get slightly more numerous, because big-headed babies are surviving childbirth better now. But the smaller-brained individuals are also surviving and breeding better, so that might cancel out the former.
Women might get slightly smaller hips, as the small-hipped ones are now less likely to die in childbirth, and more likely to pass on their genes. So you might reach a stage where a high proportion of people are born by caesarian section.
Of course, in a thousand years time, it will be commonplace for babies to go to full term in an artificial womb, so women won't have to give birth at all. So the size of babies, and their heads, won't affect their survival and breeding chances.

While there is a market for shit, there will be assholes to supply it.
