We do not understand genetic code as code. We merely have developed some statistical relations between some part of the genetic code and some outcomes, but nobody understands the genetic code good enough to write even the equivalent of āHello World!ā.
Gene modification consists of grabbing a slice of genetic code and splicing it into another. Impressive! Means we can edit the code. Doesnāt mean we understand the code. If you grab the code for Donkey Kong and put it into the code of Microsoft Excel, does it mean you can throw barrels at your numbers? Or will you simply break the whole thing? Genetic code is very robust and has a lot of redundancies (that we donāt understand) so it wonāt crash like Excel. Something will likely grow. But tumors are also growth.
Remember Thalidomide? They had at the time better reason to think it was safe then we today have thinking gene editing babies is safe.
The tech bros who are gene editing babies (assuming that they are, because they are stupid, egotistical and wealthy enough to bend most laws) are not creating super babies, they are creating new and exciting genetic disorders. Poor babies.
That is cool.
I am not a geneticist, but I have had reasons to talk to geneticists. And they do a lot of cool stuff. For example, I talked with geneticists who researched the genom of a hard to treat patient group to find genetic clusters to yield clues of potential treatments.
You have patient group A that has a cluster of genes B which we know codes for function C which can go haywire in way D which already has a treatment E. Then E becomes a potential treatment for A. You still have to run trials to see if it actually has effect, but it opens up new venues with existing treatments. This in particular has potential for small patient groups that are unlikely to receive much funding and research on its own.
But this also highlights how very far we are from understanding the genetic code as code that can be reprogrammed for intelligence or longevity. And how much more likely experiments are to mess things up in ways we can not predict beforehand, and which doesnāt have a treatment.
