Of course we won't stop thinking, creating, conversing, and there will always be hobbyist and academic interest in even obsolete skills. But we have already forgotten how to make, how to farm, etc. I don't think any single person can make even something as simple as a pencil, from scratch, let alone something like a cell-phone, advanced drugs etc. Even bringing together a collection of all the necessary experts, the task would likely be almost impossible without computers, and the rest of modern infrastructure. If humanity were to be somehow detached from even today's infrastructure, we'd be in trouble.
