Nice to know we're doomed ahead of time.
Humanity had a bad run.
Truth be told we had a good run..
Consider that our oldest civilization dates to around 4000bc with Sumerians..
And the biggest environmental damage has been introduced in the last 90-100 years, I reckon we had a short run if we consider median spices age in old times, but we had spectacular achievement as a species when we compare ourselves to dinosaur of any epoch..
We thrived, developed and ultimately it might be our insatiable thirst for pushing forward and always scaling higher and higher that will be the source of our demise..
Could we have done better? Of course..
But consider what we managed to do in 6000 years..
We formulated mathematics and physics and chemistry and other science to give reasons or reasonable speculative reasons to why not only the world around us, but the entire universe worked..
We are slow ass mammals, and yet we invented tools in their own league that allows us to traverse the world (or the space, although at an high price)...
We have splendid minds but we invented means to enlarge our capabilities (computer calculators)..
When most people think about internet they don't understand how much of a monumental thing it is infrastructure wise..
Sure we had quite some (a lot) of blunders , but let's not kid ourselves into thinking that we amounted to little or that we created nothing of value..
Apart from science and technology we created art, we created things of beauty via paintings and architecture and books..
We crafted worlds with our words, we crafted them based on existing situation and some instead we created out of thin air..
I'm an upologetic lover of humanity.. we have our faults, we have wronged each other throughout the history both one race to another and one human to another and we still continue doing so, but I seriously cannot understand the amount of self loathing that is infecting people nowdays...
