The world would become crazy, so it would be almost impossible to live among humans, that would be in panic and wouldn't be able to think (even less than now!) so I would:
  1. Collect all the information I can in a laptop, book reader, tablet, etc.
  2. Buy all the food and tools I can.
  3. Buy a 4x4 car or truck-motorhome.
  4. Retire to the most remote place I can find with water and deep caves.
  5. Build a refuge and wait for the end, meditating a lot.
That's it.
