Old concern, but it really doesn't work that way. Genetics don't respect human ideas like "nationalities" or "borders" - the targeting you can get by selecting on singular DNA variants is coarse enough to make ICBMs look like precision weapons. Like many things of this nature, people keep bringing it up because it sounds Very Scary and Very Dystopian - not because it's worth giving an actual fuck about.

I mean maybe not right now, but in 100-1000 years a complicated enough "nanobot/virus" could possibly be made to target a single person

We already had this. It was called Theranos.

I'm not sure what this comment is trying to say. Theranos was a company build from the ground up on fraud. Apple, for all its faults, is provably at the forefront of technology used in personal computing devices.

I think you've captured exactly what they are trying to say

Over on reddit people were debating whether cancer should be cured since it disproportionately affects rich people and it made me realise how far reddit has fallen. It's just a botnet now to manipulate elections.

Just spend 15 minutes in /b/ and everything else will feel better.

If it's year 2126, and you have this kind of tech floating around, and you aren't equipping the entire population with artificial immune systems capable of dealing with known and unknown biological threats? You've done something wrong.

CRISPR is an extremely overhyped approach which found a marketing engine via popular science. There is 1 FDA approved CRISPR therapy as compared to 7 for AAV and 7 for Lentivirus. Counting all viral vector therapies that have been approved, we’re sitting at 19 approved therapies versus 1 for CRISPR. I think CRISPR ideas in a lab are just an easy way into the mainstream press, but viral vector delivery is the real fut…

CRIPSR was a game-changer for genetics research. A lot of gene knockout studies use CRISPR. However, it was always weirdly overhyped for clinical use from the beginning and this was obvious to anyone with a genetics background.

The public in general doesn't have a good understanding of basic genetics and I blame high school science curriculums for not covering it well enough. Too much time is wasted on Mendelian genetics without covering the Central Dogma.

You basically cannot "edit" your somatic DNA in a meaningful wholesale way since every single cell in your body has a copy of the DNA, and it's a foolish endeavor. What you can conceivably edit to good effect is your germline DNA, stem cell DNA, or modify mRNA expression (e.g. retinoids; yes putting retinol/adapalene cream on your face is "gene therapy"), or introduce foreign mRNA for your translation machinery to co-opt (e.g. mRNA vaccines).

You're correct about CRISPR Cas9. The off-target affects are difficult to manage. The paper describes Cas12a2. This is a different mechanism with discovery origins in - of all things - agriculture. It does not attempt in any way to reprogram cells. It uses a guide protein to locate a specific mutation with exacting precision and, when it activates, unleashes total destruction of the cell. The implications of Cas12a2…

I know nothing about this field, but I imagine the actual problem is how do you deliver the Cas12a2 protein to each individual cancer cell compare to a viral gene therapy?

Devils advocate, I also vehemently shat on RNAi therapeutics a decade back. We do have RNAi therapies in market now though. I do think Crispr will find its place similarly.

“Virus” - that’s why.

After we launched our startup, we had all sorts of folks reach out to sell their GTM services. I went with one group from Vietnam that would make engagement bait Reddit questions with some accounts, and advertise our product in the comments section with others. It was expensive but it worked

Reddit is a huge danger to society. There's no doubt that subs about specific non political (and non popular) topics are hugely beneficial, the overall damage the echo chambers do still outweigh these benefits.

Well, now that it's becoming "the community source" for LLMs it's becoming even more of a target for large-scale manipulation.

Edit every cell? No. Edit enough cells to impact health outcomes for a meaningful period of time? [Yes](https://www.youtube.com/watch?v=J3FcbFqSoQY)
