As with many things, the problem is not technological. We have the technology to create such a utopia (there would still be other problems, but the world would be utopian from those aspects). The problem is sociological. In order to do this we need to both all work together, and think long term (on the order of 50-100 years). The problem is that nations can't even stay together in just an economic union when it's in their best interests economically (Brexit, Paris Accord), and internally those same nations bicker and vote on party lines (Tories vs Labor, Democrats vs Republicans), instead of voting what's best in the long term for the nation.
What's happening in Texas right now is an example. Texas had the money to buy snowplows. They didn't. Texas had the money to winterize wind turbines. They didn't.
We have to get beyond our short term greed and work together in long term action to succeed at addressing these problems. Otherwise there will always be Epsteins, etc. in any industry where people are vying for attention (most of them).
