Pshaw .. they've been doing this for years, except in reverse.
How else do you explain many of our politicians?
Seriously though, very interesting.

..."We need to be able to watch it, consider it, discuss it and stop it if we think we think one day we are at the point where we shouldn't progress," she says. "I think we are far, far away from that point right now."
Even the most advanced brain organoids have nothing even remotely like the capabilities of a human brain, says Hyun, who posted a video conversation he had with Pasca to coincide with the publication of the new study.
Yet many ethical discussions have focused on the possibility that an organoid could attain human-like consciousness.
"I think that's a mistake," Hyun says. "We don't exactly know what we mean by 'human-like consciousness,' and the nearer issue, the more important issue, is the well-being of the animals used in the research."
He says that wasn't a problem in the Pasca lab's experiments because the organoids didn't seem to harm the animals or change their behavior.
If human brain organoids are grown in larger, more complex animal brains, Hyun says, the cell clusters might develop in ways that cause the animals to suffer.
"What I'm concerned about," he says, "is what's next."
