You'll pardon my cynicism.  In the 1950's, the "experts" said we were ten years away from fusion energy.  In the 1960's they said we were twenty years away.  In the 1970's, we were now thirty years away.  In the the 1980's they finally wised up and stopped predicting.  I'm still waiting for the flying car I was supposed to get in 2001.
