Twitter doesn't do my dishes, or cure cancer. It just lets people communicate, like did the telegraph 200 years ago.
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.
Your dishwasher does your dishes, and chemotherapy cures cancer.
It'd just be nice if my dishwasher did my dishes better, and chemotherapy cured cancer better (and less painfully).
Kinda like how Twitter lets people communicate better. New products are almost always a refinement of some existing product. The ones that aren't tend to elicit a big "Huh?" reaction from the marketplace.
I'm sorry that you see the world that way but not everyone can cure cancer or build robots and to be honest most don't want to.
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.
