While this technology’s intent is to treat disease symptoms, it’s easy to see how it could be hijacked for nefarious purposes in this fallen world. Once these devices are in the body, it would be difficult, if not impossible, to remove. It’s not hard to imagine a future antichristian spirit exploiting this technology.

Not difficult or hard to remove , just stick your head in a microwave.. or maybe an mri scanner can magnetically remove them.
