It's all coming together, anthropogenic planets, anthromimetic algorithms and of course extraterrestrials.

The science-fiction scenario of an artificial planet is already here

"The global mass produced by man exceeds all living biomass. We find that Earth is exactly at the crossover point; in the year 2020 (±6), the anthropogenic mass, which has recently doubled roughly every 20 years, will surpass all global living biomass."

Teaching AI agents to communicate and act in fantasy worlds

They're called Agents. And they live in simulated realities. One day they'll invite us over for dinner.
"Researchers at Georgia Institute of Technology and Facebook AI Research have recently explored the possibility of equipping goal-driven agents with NLP [natural language processing] capabilities so that they can speak with other characters and complete desirable actions within fantasy game environments."

Using game-theory to look for extraterrestrial intelligence
Oct 2020, phys.org
The SETI paradox says that we haven't discovered signals from aliens because they're afraid it might draw the attention of adversaries. But game theory says that the one who has the least to lose signals first. Or in other words, the one who has more access to information signals first.
Unbelievably, this narrows the search down to just one exoplanet: K2-155d. It's suggested that because it's more visible to us than the other way around, that we be the first to send a signal.

Partially related, my theory for world peace is to unite the world against the probability of an alien race attacking Earth. I take this idea from the book Three Body Problem where they spend hundreds of years preparing for the arrival of an alien race that may or may not destroy them. All the resources of the entire population of Earth are brought together to solve this problem.
There can't be world peace without a world enemy. So we should create one. Or rather, the probability of one. Which shouldn't be too hard. What's the chances, and how far away are they, and so how long would it take for them to get to us. Now we work backwards, and set a long term plan to solve the problem, together.
