"short lifetime" is relative. Had Apple been granted a patent on the idea of a smartphone the same year they released the iPhone, that patent would only expire in three years.
There are some industries where due to slow-moving markets the 20 year patent period is still sensible, but for most sectors we would be better off with a 5 or 10 year patent period to account for the increased speed of innovation.
