"You must struggle with your own beliefs if you are to make any progress in understanding the possibilities and limitations of computers in the intellectual area. To do this adequately you must formalize your beliefs and then criticize them severely, arguing one side against the other, until you have a fair idea of the strengths and weakness of both sides."
I do see your point though. Someone may have been thinking of this concept 10 years ago, but it certainly wasn't me.
I then had an idea using SMS and windows pocket PCs to basically make something like Uber for a software taxi dispatch system. You would SMS a number and then get updates via SMS on the status of your cab. Cabs would have the pocket PCs installed with an external GPS module. I would sell it to taxi dispatch companies as a way to make more money. I was just starting university although, and felt quite overwhelmed with the idea of actually selling it to anyone.
