What do you think the probability is of the human race surviving to the year 2150?

I have a feeling we'll be lucky to make it. The probability of thousands of nuclear missiles being fired in the next thirty years is higher than it was in the 60's and 70's. I also think that artificial intelligence has the potential in the near term to become a major threat to human survival, particularly as it is being developed in a highly competitive manner. You also add in the potential threats of climate change and pandemics. It's pretty bleak! What probability do you assign to the human race surviving to 2150?
