Return to the level of intelligence? I think we just won't be able to sustain the sophisticated complexity of our current systems in addition to the death of skilled professionals. Honestly, my only hope is in the book I have printed called How To Invent Everything and my other books about farming, food processing and weaving, then make the technologies that we can create and sustain for the betterment of any community that I find or adopts me. Then become a cult leader idk
