It's all in your perspective. The problem with the 20 year window for me is that I'm 88 years old at the end of it. I don't expect to last that long.

It makes me sad, in some ways. I've been a relatively early adopter of a couple of things (Steem among others) and I have no hope of living to see it mature and be a part of society as a whole.

At my age, a 5 year window is a long ways out...
