Here’s how I would prepare for AGI:
Work is going to become a lot less important. If you are the sort of person who ties your self-worth to what you do, I would start decoupling that.
We might live for a very long time. You are going to want to be as healthy as possible. Get scanned, MRI, blood tests. Lift weights and build muscle. Work out for an hour every day.
Your friendships and relationships are going to become even more crucial as you look outside your work for meaning. Invest in them. Have a large family.
Develop hobbies. Learn how to cook, garden. Read books for pleasure. Study that subject you’ve always been fascinated with. Learn for the sheer joy of it.
Spend more time doing your favorite sport. Skiing, kite-boarding, tennis, whatever it is.
And marvel at your good fortune to be living through such a historical time.
