C may let you shoot yourself in the foot, C++ may let you blow your whole leg off, but only CRISPR will let you turn it back into a tentacle.

So maybe The Thing was an alien CRISPR experiment gone wrong.

I share the worries of "messing with things we don't understand" but that comes after not accepting this practice of using conscious beings who can experience pain as objects. It's inventing more suffering on purpose, intentionally breeding animals that were born to potentially suffer. Breeding animals in general always has a chance to result in painful deformities but this is treating them like they don't matter.

Article says they are using an "older method" of gene editing. Well no wonder then, we know that older gene editing methods have a lot of off target effects, crispr cas9 using base modification (instead of deleting whole DNA stretches by splicing) is very safe. This is a FUD article.

Base editors are a very new (first published in the last two years) and have a whole new class of off-target effects compared to the ‘standard’ Crispr-Cas9 approach, namely editing multiple bases in the targeted regions.

I’m not sure why you would say that’s base editing is inherently superior to homologous recombination at the point in time.

From my laymans POV, DNA is just a shit ton of variables in a very complex code that interact with each other. No single point just does a single thing. They all interact with each other. No different than changing a variable in one piece of code and having it create a bug in another that was previously working. For me, the real scary part is altering something, which inadvertently changes something else that isn't q…

That actually makes cronix' point.

> Something like "everybody will get Alzheimers by age 50" where it takes 50 years to even discover it. Yup, and my then the market is established and the companies creating the market will say it's impossible to know that the side effect was actually caused by altering your DNA, and go on knowingly selling services that are destroying lives all in the name of money

So, look, don't do this.

This isn't about whether and to what degree "companies" are cartoonishly evil. And when you divert the conversation into that very well worn path, you distract from other problems.

There are lots of threads on HN where complaints about corporate ethics are on topic.

That genetic modification can, and does, happen naturally, all the time. It’s how evolution works

That talking point has already been attempted by others. Using one term, genetic modification, for several completely different processes doesn’t hide the truth, it just confuses people. And no, grafting entire sections of bacterial DNA into plant genomes absolutely does not happen in nature. Please read the link, then get back to me with any actual scientifically founded refutations you may have. Citations are throu…

That’s exactly what the article you linked to does too. The takeaway is that any alteration to the genome of food is bad.

GM foods are arguably no more dangerous than any massively engineered foods we've been eating for decades/centuries. Direct gene modification is more like using a scalpel rather than a 2x4. Still potentially dangerous, but far more precise.

"GM foods are arguably no more dangerous than any massively engineered foods " This may be your opinion. While GM foods are not per see dangerous, the long tail risk is tremendous, exactly because you can not tell what a gene is going to do in another organism. Take my word for it, I have a PhD in that shit. Taleb also advocates the precautionary principle: https://arxiv.org/pdf/1410.5787.pdf

Speaking Risk, Rob Reid wrote an interesting series of articles, one of which was on global risk that this topic made me think about https://medium.com/s/powertrip/the-50-50-murder-a3832f587bee

Sounds like it's time to refactor that system into something less crazy. Or better yet, rewrite it in Rust.

That system is incredibly efficient and dynamically stable.

In keeping with the analogy, what you're saying is that the build system and deployment system are extremely complex and have a lot of parameters.

You just described the plot of Prometheus too.
