Rushing into the Future

I have always wondered why technology has taken off and advanced so far so fast in the last one hundred years. Then all of a sudden technology began taking off really fast in the last 50 years. Well fool me again look how fast technology sped up in the last 25 years. Now it is a daily quick sprint turning into a run . So why does mankind all of a sudden have to advance so quickly into the future? Why now? Is man preparing for a major storm or something. Could some great subconscious mankind reawakening event occur? Maybe it is all those high energy drinks like Rock Star? So what the heck is the rush?
