Asking this question is ignoring equally significant advances in human history. The invention of the computer is basically dependent on the invention of agriculture, if you go far enough back. Most people don't seriously contemplate if we are perhaps too dependent on agriculture and what it would be like to go back to being hunter-gatherers, though I've met at least that did. Also, the idea of all our technology ceasing to work is about as unlikely as all our agriculture ceasing to work. I'm not saying it's bad to ask these questions. It's not. It's good to ask them. But we need to keep in mind the broader context. (Some other inventions to consider: the steam and later internal combustion engine, the electrical generator on which all modern technology depends and the related battery, the printing press, pasteurization... the list goes on.)
