The future could be interesting. only if I could go beyond 100 years and return soon after because I feel that AI will be the dominant species, but I wouldn't mind seeing how that works out.
I would however MOST Definitely Love to go back to the past and come forwards again from when life REALLY WAS very very, exciting. I would """AVOID""" meeting my ex-wife most definitely!!! Ha Ha Ha. And I would both repeat, and I would change, many of my past in the moment decisions.
I would hopefully also fall in love with an adorable like-minded someone who feels the same and we both would experience ongoing financial abundance early and do truly great things with this massive wealth.
With it, I would for instance, do whatever I could to improve the lives of people everywhere by creative inexpensive innovative long lasting modular housing designs and the Global business to support its creation and distribution and then go live a shoes-off creative mutually supportive gentle life on an isolated island for 3/4 of a year with likeminded others and let it evolve.
Yep, I would most definitely go back in time.
