Except for chance random mutations, it is highly unlikely that the human brain will evolve to be larger and more complex in such a short time, by evoultionary standars. Current standards are likely to remain unless the mutations occur and prove to have beneficial survival value. I wonder if better nutrition and the rise in obesity in the world’s population is not likely to increase average body mass, so if no increase in brain mass takes place, we might actually end up with a smaller brain-to-body mass ratio.

Evolution doesn’t normally move that quickly. Brain size started really increasing about 3 million years ago. It took a couple of million years to approach our size. The only way to get rapid evolution is a massive die off or selection. That would obviously be a bad thing.

Well the average could increase a bit as a result of (hopefully) better nutrition in the world.
Malnutrition is one factor that can lead to a decreased brain size (on a small amount), so if the nutrition situation changes drastically, the average brain size could as well change, though we are not talking about high numbers here.
It will be the same. It would only be different if the dumber humans (with lower brain weight I guess) were dying off and not able to reproduce due to not being competitive enough, and thats clearly not happening

about 0.5% – 1% increase.
