It means evolutionary pressure will increase and accelerate. Modern science will allow couples to genetically alter/select for best embryos. It will be a genetic arms race to produce the taller, faster, smarter, healthier, etc children
People choosing which traits to optimize for isn't evolutionary pressure. Evolution is a very specific mechanism that optimizes through random mutation. Choosing what to optimize for, using science to continue 'undesirable' genetic traits, making people choose who to reproduce with by manipulating what's considered attractive through Pornhub and Instagram, etc are all ways humans are now a poat-evolution species.
The fact we happen to still pick the traits that evolution optimized for in the past is because this is something that's only happened very recently. We're only just starting to move past evolutionary pressure. We could select for anything through science and tech. The fact we'd probably go for things like height, intelligence, etc just means we're not being very imaginative. One day we might decide to push for smaller offspring so we can fit more of them on spaceships, or for children who can survive with less water because the climate is screwed, etc.
The outcome will be the same as evolution, eg optimizing for the survival of the species, but the mechanism that causes it will be very different and absolutely not evolution.
If anything, what you describe is intelligent design, just by humans instead of a god.

It sure is. Look up selection or selection pressure ( another name for evolutionary pressure ).
> Evolution is a very specific mechanism that optimizes through random mutation.
Random mutations are meaningless without selection pressure. It's the selection that drives evolution not random mutations. You could have evolution without any mutations - the environment could change which selects for certain existing traits.

Which is called evolution. You seem to have a misunderstanding of what evolution is. Evolution isn't only "natural selection". Artifical selection exists. For example, dogs evolved from wolves by human/artificial selection, not "natural" selection. Regardless, it is still evolution.
