I'd be more worried about how close the end of life as we know it due to climate change is. 2050 is going to be a hoot.
The rest is probably slated to come around 2100 by which time we might not even have the society and tech to make those things, due to the breakdown we will have experienced long before then.
A lesson the left doesn't ever seem to learn. The worst enemy of the left has been, is, and always will be, the left. The infighting is insane.
I think the problem is that the right is unified in hate. It's a very simple, very basic emotion, that's mixed together with tribalism and group think. It helps people create a bonds as well as an "us vs. them" mentality, which is very strong.
People on the left however are split because they don't want to hate, they want to be inclusive and tolerant. That however is very difficult when someone hates you and is intolerant. You can't be tolerant of intolerance, love hate, and include exclusiveness. However, being intolerant of intolerance, hating hate, and excluding exclusiveness creates a cognitive dissonance. The left is very capable of hate, exclusion, prejudice, etc. as they are humans, but because they aim to become "better" than the conservatives, liberals, etc. they create large divisions in their groups that can't overlook their differences.
And will forever be a problem of the left. Being better is difficult.
