Who causes the end of Human Civilization this century (all humans don't die just human civilization)(at least as we presently know it)

I think if you were going to name names the cause would be Putin, Xi, and Trump would be the biggest names in the end of human civilization.

However, it isn't something that they are trying to create. What happens is a bi-product of what they are all doing not something they are trying to create. And it isn't a "World war III" it is the slow degradation of everything to do with human civilization.

We are seeing the first parts of it right now through Global Climate changes and Trump trying to hide these global climate changes so Billionaires can profit from these Climate changes without enough people having enough scientific knowledge about what is causing their mass deaths worldwide. So, as more and more people die of ignorance worldwide most people are just scared of dying more than anything else and completely ignorant of the causes of their deaths.

In the process of global Climate changes on top of the planned ignorance of the masses for the profit of billionaires around the world people begin dying like flies faster and faster and faster.

Then the machines start to take over in the military and in manufacturing so many people starve to death with out jobs worldwide since billionaires no longer need the average person to be their slaves. All they need is enough techs to build Air, land and sea and Space Autonomous Drones.

At some point the drones begin killing both the billionaires and the middle Class and poorer people. Why?

There is really no reason why really because machines have no compassion. They just do whatever they are programmed to do.

And you really only need a few Autonomous robotics of Air, land, sea and Space to totally end human civilization.

Here's an example:

GReedy billionaires want the good farmland of people around the world so they decide to steal their lands.

How? By sending in drones with something like hellfire missiles to kill them whenever they go into their fields to farm.

What happens?

The people in those communities that can only afford local food begin to starve to death even as the billionaires steal the land of Farmers who are still alive and got smart enough not to farm to stay alive.

This will be repeated over and over again all over the planet using various kinds of military drones. It will start with Drug Lords and work it's way up the food chain to people like Trump and Putin and Xi until no one owns anything at all because if they do they will be killed by one of the drones owned by people like Trump and Putin and Xi.

This is what is coming this century from Autonomous robots for humans of earth.

Can this be stopped or changed?

I'm not sure but the reason I'm writing this is in the hope that enough people can figure out how to stop this from actually happening because this is beginning already in Ukraine and Iran right now.

IF this presently continue the way it is all people in Ukraine and Iran will be dead within 10 years.

This has to stop with Ukraine and Iran in order for civilization not to end this century.
