股市：我應該可以說是做高科技的 但是我常常對新的高科技東東

沒有廣大群眾信心那麽大。在這壇裏我潑過冷水的有 solar, 3D printing, IBB, social media ... 還有”可穿戴的“。 很多人知道 UP (made by Jawbone). 我了解其核心技術，基本是忽悠。下麵這篇文章有這樣評價 which I think is correct and funny 

 

They're just toys. Expensive, cool and ultimately useless. If you're tired you need more sleep. You should walk more. If you don't go to the gym or exercise regularly a smart watch won't change that fact unless it comes with an app that lightly electrocutes users as a punishment for sloth.
