Looking at the current political climate in the US anyways, I don't think there's a chance of UBI for a very long time, if ever.
There are too many people who are totally committed to obliterating any sort of social safety net, even if it is directly against their own self-interest. Income inequality will just continue to get worse. Jeff Bezos will be a bazillionaire, along with a few other people. Pretty much everyone else will be SOL.
Eventually, after enough starvation, there will be riots and massive violence, and most people will be killed. I don't think it will be some alien organization taking over, we will eat our own instead.
I probably didn't help with the insomnia, sorry.
