- Tor3 8y agoAs I recall they all had positronic brains from the beginning, but the factory that created them used programming on paper tape to feed into whatever created the brain pattern. I vaguely remember a plot that was about some school class visiting the factory and a boy managing to fiddle with the paper tape and change the programming.
- cgriswald 8y agoThis is where the reader’s imagination can fill in the gaps. Paper will survive magnetic fields , heat, and rapid changes in temperature that traditional storage won’t. It’s also cheap and disposable. Maybe one or more of these is an issue when trying to cost-effectively get the initial programming into these things. We conveniently don’t really know how they work.
