Voted "Never" because:

1. It will likely take at least multiple generations.
2. By the time they can create a Thinkpad, they will already have a lot of technology and infrastructure.
3. The generation that has the ability to create the Thinkpad will have no connections to the old world. They will not want the new world erased in favor of the old world. Thus, they simply won't create the Thinkpad.
4. The new world will simply continue on according to its natural development.
