Nineteen year from now. [en.wikipedia.org]
I don’t expect to still be around, so have at it. Predictions are generally not worth the space they take up, and the lead up to collapse will be as bad if not worse than the finale. And at the rate things are going, I may have to live through that. But our parents made it through WW II, the Great Depression and their pandemic. We made it through the civil unrest of the 60’s and 70’s, the Cold War and four years of Herr Trump. I guess we’ll just have to do what people always do, the best we can.
You'll be 88 and hopefully still around. You can let future generations deal with it, and spent your time enjoying a long retirement. I'll be old too, if I'm still here.
