I've been here and here to learn what (not provided) means. Now the question is if what I am seeing in my Google Analytics stats for my website is considered normal (and whether I can/should do anything about it).

Here are the statistics from one day, but other days are similar:

102 visits, 57 is from (not provided), that's over 55% of unknown keywords.

Is it normal to have it like that? Does google plan to do anything about it? In other words, what's the perspective? In my understanding, with this approach, as people switch to https, Analytics will stop being useful. Please correct me if I am wrong in my assumptions.
