GenX is tiny and has failed to progress forward precisely because it is so small compared to the Boomers and Millennials. Also by the end of the decade parts of GenX will be approaching 60.
The United States - and really the world as a whole - has enjoyed its most prosperous time in all of human history during Gen-X's window of contribution.
Long to short, the jury is still out on the actual success of Gen-X.
The climate has changed and will change. Some of that change (although I think its a small part) will be influenced by human activity. The Earth will adjust. Humanity will adjust. And humanity will continue to flourish.
p.s. Humanity will continue to flourish? Your prediction is based on what, past performance? When Mother Nature's bounty was harvested mindlesssly and shameleessly? That's going to continue forever? Infinitely? Can you share some links supporting such projections?
Did I stop aging at some point and not notice?
What you need to realize is that Gen X is stuck in a crack in time that halts the aging process for them. All of them. A side effect of this is that while they can interact with the world and almost be perceived, they actually have been forgotten by the rest of the world.
On occasion a regular aging schmuck will notice a wild Gen Xer and be able to interact with them whilst the Xer is within their field of perception, however these interactions are invariably fleeting and almost immediately forgotten for it leaves the regular person’s body and mind in a strangely exhausted state. Interacting with a forgotten person stresses the body, and so while someone may not exactly know why they wish to flee from this person that seems like another person, at some point the brain sends the neurological equivalent of a kill -9 to end the conversation. It is estimated that about 200,000 Gen Xers are killed a year in this way, but nobody has been convicted since 1. nobody has been able to find the bodies again and 2. Even if they were, it would probably be ruled as self-defense and 3. All memory of the events that transpired invariably slips away from the living.
