If the average human in twenty years isn't far more cognitively capable than the average human now, I'll eat my hat (assuming of course, we don't all die).
Between biology advances remediating disabilities, customized outcome-driven education, potential advances in drugs that regulate executive function/memory/etc., improvements in nutrition, improvements in access, reductions in stress, I think we'll see people flourish.
And that's completely ignoring the more out there biological/computer merger style Sci-Fi outcomes, which I believe have a non-zero chance of occurring.
