Reinventions of the telegraph (twitter/facebook) and operating system (apple/android/chromeos) is all i'm seeing these days.

If you want the problems solved start working on it yourself it isn't other peoples burden.
Operating system snark - beneath os x and android is unix, invented over 40 years ago.
I do work on it myself, but i'm only one man. If the industry set its goals higher that would make a real difference, and put more money in its pocket.
If you are using any operating system other than the unix invented 40 years ago then I think there is a reason for new operating systems and I stick with my opinion. An airplane is just based on some flying contraption people built 100 years ago but there is a reason we built new ones.
It'd just be nice if my dishwasher did my dishes better, and chemotherapy cured cancer better (and less painfully).

Criticism is what makes science function and is what made the west great.
