Scientists grow bigger monkey brains using human genes, replicating evolution

Actually it does. It's quite likely that this is neither the first universe nor the last. But it's certainly one of the more stable ones.

> If anything, that makes nature the one that was blindly messing around.

Quite hard to image that something even close to this has happened by pure coincidence - e.g. mutation - before.

I didn't appreciate the wisdom in that joke until my kids were teens. The sadness comes from the expectation of the painful times between the onset of the technology and the eventual successful integration of that technology into our lives. For me, I live in Silicon Valley which has more superfund cleanup sites than pretty much anywhere because the chip companies dumped a lot of toxic chemicals that later turned out to be carcinogens into the ground. People I know, some well, some only by association, were harmed by that. It was part of the "learning curve" of developing semiconductors which have so changed everyone's lives. That the chips are a net good is, in my opinion, pretty clear. However, the "learning" of the superfund cleanup was painful.

Bespoke genetic manipulation will have similar "growing pains" and those pains will kill people, cause generalized harm, and likely a catastrophe or two. And once we've gone through that and understand the risks and challenges in a more fundamental way, then people will be enjoying the benefits and the risks will be contained by legislation or some other oversight.

Yes. I would call it extremely irresponsible -- on the same level as having a child you know you will be unable to feed, so the child will starve and probably die. (With the same excuse: but wouldn't the child be happy that they existed at all?)

We have no idea how different species would think and feel. If we imagine them as "exactly like humans, only with more fur", well, who knows, it might turn out to be true; but if it is not -- if the difference between us and them is greater than the difference between any two humans, just like with the biological differences -- then we might create another intelligent species with incompatible values. Where "incompatible values" could mean that a reality that makes us happy would make them unhappy, and vice versa, so there is no outcome that wouldn't require lot of suffering.

The assumption that they would be "exactly like humans, only with more fur" makes sense from a Cartesian, dualistic perspective. Same souls, in different bodies, duh. But if you think that mind is a product of body, and tiny changes in the body can have dramatic impact on how the mind works, e.g. having more or less of some hormone can profoundly change your personality; then minds of different species will probably be quite different.

Then there is this practical problem, that we can't even take care of our fellow humans. People are still starving, dying in wars and genocides, etc. Even in first world we have the problem of poverty, racism, whatever.

Now imagine that into this world you introduce a new intelligent species, which might be incapable of getting a job, dealing with bureaucracy, or just interacting with majority humans in ways that humans consider acceptable. Because this society is designed for humans, it might be impossible to navigate for them. Then what? Keep them in... a big ZOO, forever? Tell them the same fate awaits their kids, and the kids of their kids, until perhaps one day humans get bored of them and decide to exterminate them? Or let them out, and then put them in prisons, because they may be unable to abstain from behaviors that are considered criminal by us? Require them to ignore their own insticts and live accordingly to our instincts, and then punish them if they are unable to comply?

Or are we going to give them an island where they can create a civilization according to their own norms? And ignore if they decide to do things that are abhorrent to us but normal for them? Are we going to trade with them? According to their norms or ours?

The only reason this works in some sci-fi books is that the other species are "exactly like humans, only with more fur". It may not work if they are fundamentally psychologically different.

If the new species is capable of communication with us, then it doesn't really matter if they think like humans or not. In fact, they are much more interesting and valuable to us if they don't. Differences in values, territory, what they need to be happy, all of that can be worked out through negotiation and communication - or not, and we can just give them space and avoid our own interference as much as possible, while providing the resources they need.

I think it's important to emphasize that you're right - bringing a new species into the world as it currently stands with massive inequality and many human problems left completely unsolved isn't a good idea. Doing so after a post scarcity society has formed and there are enough resources to go around (not all that far off...) - much more reasonable. Expecting a new species to just magically integrate with society and "get jobs" is a little silly here. I think we need to differentiate the moral problem of eventually increasing another species' intelligence capabilities in the future under our best efforts at responsible conditions - vs doing so right now in this shitstorm.
