Apologies for the messy reply, I was interrupted several times while trying to type that out. I generally create cleaner responses.

Hi Len. “Humanity” is an interesting word to launder our basic animal nature. I refer to the medieval period because today we have the same obscene biased system (the only thing that changed was technology): an unnecessary social caste systems, State obsessed ownership of everything (including people, or ‘citizens’, as property to exploit), greedy banking systems that take pleasure in creating poverty and starvation etc., taxes (protection money or else), annexation, hypocritical and undemocratic laws etc., “sanctions” (aka a medieval siege) and general war lust to take other nations resources by force etc. Only to waste said finite world resources on making pollution for overpriced disposable consumer junk, rather than making cleaner fair priced high quality goods that everybody actually needs (and could have).
Bottom line is that we are a group orientated animal species governed by the crazy Alfa tyrant parasites (aka the “elite”). Humans are dumb animals with egotistical delusions of grandure. While we are animals (no escaping that fact), that is no excuse to act like barbaric selfish thugs. We have potential to be better than this but the greedy psycho’s in charge sabotage all the good in society, meanwhile everybody just lets them. If the criminally insane are not removed from power, we are a doomed species. It is a miracle we have made it this far in an age of mass destruction tech. Maybe “The Great Silence” says more about our fate than of aliens ?
As corrupt world politics currently stands, selfish consumerism for a tiny minority’s wealth gain and the rise of antisocial behaviour etc, humans can’t evolve to reach a more advanced form of civilisation never mind a T1. We still have hunger, homelessness and no quality global free healthcare in 2023 !
Climate is always changing regardless of humans, it is the man made pollution and pointless destruction that is the issue. Most people don’t realise that we are still coming out of the last ice age, expect it to get much warmer. We are now entering the solar springtime as the final ice caps melt, hard to believe but Alaska used to be a tropical jungle full of dinosaurs and broadleaf plants !
Polluting the oceans, creating virus weapons and setting off atomic bombs is not a smart move. No advanced civilisation would commit such crazy actions because that would be suicudal for the species.

Hi David, Have we progressed beyond our basic human nature let alone barbaric medieval age mentality? Some of us have. The problem is not everyone of us who call are selves humans, act with humanity. It is interesting that the word “humanity” is derived from “human” when we know that much of what makes us human can be deemed to be undesirable. As for achieving a Type 1 civilization by 2100, my hope is that we finish this century with an Earth that is still recognizable after anthropogenic climate change begins to do its worst.

Speculating on the billions of years in which life processes have existed here on our planet Earth, and probably on numerous planets throughout the Milky Way and other galaxies, one would think we would through SETI and other observations have discovered intelligence elsewhere. Maybe it is the physical limit of Einstein’s mathematics that keeps us and other civilizations bound to a finite limit of expansion.

I hope that our other world experiences will not only exist on holodecks.

Long before any civilization could consider interstellar travel, technology for virtual realities would have evolved to the point that holo-decks could instantly transport humans to infinities of virtual worlds. Mankind is not going to the stars. Mankind’s technology is going to create and bring the stars to itself.
