Important point. Pretty fucked up to do this to a human.

At the embryo stage, what's the difference?

It's the abortion debate. I'm against abortion. The way I see it is a person has rights no matter the person's age. Earlier in development just means younger.

Wouldn’t the living artifact that results from this embryo just be horribly incompatible with life and die quickly or at best live for a brief time before expiring?

I suspect we will find out at some point in the next 25 to 50 years. Somebody, somewhere, is going to give it a good try. As in not stop at just the embryo stage, but make fully functional living beings, regardless of whatever laws exist. The ramifications of "synthetic life", will sure to be staggering. This was covered a bit in the Blade Runner Sci-Fi, but what real Replicants would be like and what they will do wi…

People always say this, and yet the universal ban on human cloning has, at least so far, held strong and prevented further research more or less entirely.

Possibly? I expect we'll figure out how to do this with a high chance of success within the next few decades if not sooner, unless for some reason every country capable of supporting the research bans it.

Human cloning research has similarly been banned, and quite successfully, hasn't it?

Not a human, just a thing made of human parts.

...and that kind of thinking illustrates the kind of dehumanizing attitude that is harmful to the "products" of such experiments, such as the person that would develop from such an embryo. Very worrisome research.

Assuming the embryo eventually developed, it would eventually become a person. But just like sperm and egg cells are not persons, and fertilized eggs are not persons, embryos are not (yet) persons.

The OP posted an entirely mainstream hypothesis. Let's not gatekeep and rely on credentialism.

First of all, it is a hypothesis even if mainstream. What if pregnancy failure has nothing to do with fitness? At this point we do not yet know.

Now explain why we should remain unknowing instead of spending effort to find out.

No name for this research project was mentioned- may I suggest the Nexus-0?

Replicant number zero. This research is terrifying to me because life is never within our control. What kind of life is it if a mouse or human is reproduced without parents.

What makes this so terrifying for you?

Many things were not within our control and yet now they are.

I find the term person to be key here.

In that case you should very much be in support of this research.

According to you, those dead embryos that resulted from failed pregnancies have just as much a claim to healthcare as anyone else.

This researchers that problem.
