Sure. Like I said, you can do this at any point in time and if enough people do that it becomes a self-fulfilling prophecy so it's better not.
Out of curiosity, I took a look at your submission history (which is vast!) and it's 90% doom and gloom across a vast array of topics. I do think living with such a negativity bias is very disempowering - and not to mention not fun. I don't mean to be stupid and blindly optimistic (I manage risk for a living among other things) but like I said, living with certainty that everything will be terrible will ruin your life.
Like I said, since dawn of man, people had reason to believe what you believe. And those who really believed it would have no reason to build anything, learn anything, invest in anything, have children etc - why do any of that if the world is ending.
But the world is inherited by those who DO do those things - everything we have, everything we are, everything we're investing in - is there because someone in the past believed that the future is worth the work. So just be careful how much of this your let into your psyche because it will lead to you to a dead end
