* silicon valley doesn't produce much hardware (evidence for this being true? obviously we hear a ton about software, but what about tesla, intel, nest, apple, google, etc?)
* businesses such as social networking, personal assistance services, short-term house rental services, and other saas have questionable customer value (why?)
* there will be an implosion of these saas businesses (why?)
Consider the amount of hardware that a modern smart phone replaces such as the calculator, phone, video camera, television, radio, clock...
They are producing less hardware because hardware is becoming increasingly integrated as software:
>The hardware world tends to move into software form at the speed of light.
-Marshall McLuhan
Of course, just because these things may greatly improve the quality of life doesn't mean that they'll create jobs. They may destroy them, and while so far people have found new industries and jobs to replace the ones that become obsolete, I suppose there's no guarantee this will continue to be the case in the future.
Why?
