Build a Jail on an Island and put all Politicians, Billionaires, Bankers and Rapists there (except Mindset). It would be like a soft reset, things would go back to what they are but it would take 20-30 years.

Such a ridiculous hypothetical situation but it'll be a mixture of The Hunger Games/Divergent dystopian futures mixed in with skynet robots to ensure the games are being properly carried out.

The logistical considerations on any of these things would - in and of themselves - likely take lifetimes. I'm also not sure the OPs wide-reaching goals are possible at all, short of primordial biological modification that fundamentally alters the species, or some other form of overt control. Having control of the world's governments and such isn't anything like the power you'd need to make humanity peaceful and happy. At that point you'd need Biblical and/or comic book powers to have a chance.
So I'd keep it simple. Probably the only things I'd do would be to try to eliminate the stuff we could use to destroy ourselves (nuclear arsenals, etc.), and I'd try to push education in the right direction where it's needed most. Then I'd let everything else play out as it would.
