Bitcoin...useless

I kept seeing all those posts about BitCoin a P2P digital currency proposal. I was thinking for a while, what the fuck is bitcoin? So I did my research. Junk. What do you guys think? Realistically, does anyone think this is yet another silicon valley fad? There are far too many technical roadblocks for bitcoin to receive wide-scale adoption. There will never be 21 million bitcoins at one time.
