If I was running a space ship based on exploration and I have sensitive equipment I didn't want to fall into the hands of primitive natives, I'd build these things with a short out device that can be activated by radio. This isn't even beyond our capabilities today. Or just cut your losses being if you dropped a cell phone on medieval Earth, there' not much they'll be able to do with it, especially when the battery runs out. But what do I know?
As for Singularity, yeah it's all been done before. At least they didn't all start randomly having sex.
