I don't think we're getting stupider but I think our bodies are realizing, "Hey, I don't use half of my brain anyways, why eat extra food to support it when it could just get smaller."
I'm not sure that's why.
Evolution almost always produces physical traits. This is because, in the animal kingdom, the strongest and fastest survive. Intelligence doesn't really have much to do with it. It can be argued that an ape with a sharp stick will win a fight with an ape without one, but on the grand scale, raw physical power wins.
Compare this with humans. Technology has done amazing things for us. We take in (on average) more information in a single day than most people 100 years ago took in each decade! Sure, this improves our quality of life (arguably), but evolution doesn't care. At the end of the day, the football star has a better chance of survival than most nerds/geeks.
So to sum it up, our brains are not shrinking due to "lack of use" necessarily, but rather because evolution favors strength.
Also, be advised that I totally bullshitted that 100 years thing. I forgot the actual numbers, but it's something close to that.
Also also, that whole thing about us using 10% of our brains is a joke psychologists play on their students to make us feel inferior so we study harder.

All it takes is one bear to waste me. Bears are fucking powerful. Kinda proves my "raw power" point.
