Bioethics of Gene editing, an analysis of some concerns as addressed by Steven Pinker

Steven Pinker provides some details regarding his view that banning gene editing technology outright is naive in this interview. I some times agree with what Pinker states on various issues and on this one a particular area of my research focus he does get the general reality correct in my view (that bans are naive at this point) however he's a philosopher and not a Scientist and thus has made a few errors that I will point out here.

First, the idea that crispr is prone to significant errors is false. The early versions of the technology produced by Doudna's team in late 2012 were but even then they were significantly less likely to induce errors than prior methods (zinc fingers and TALENS).

Since then far more advanced methods have emerged that are virtually perfect in make single gene modifications consistently, keep in mind that a large part of the accuracy is involved in ensuring the a sufficiently unique guide RNA is utilized to zero in on a given gene and induce a change...there is no reason to supposed that an arbitrarily long and unique guide RNA can't be utilized to target a change over a desired region. Technical issues exist in packing these longer guide RNA's with the complex machinery and vectoring them but those are hard to do's not impossible to do's, if we throw the will and money at the problem it will surely be able to go away...or at least go away to such a degree that people are willing to pay the necessary money to overcome any inherent risk. A paper by George Church et al described some of the issues with the then current process, some of which have since been alleviated or mitigated:

Our current pharmacy business is thriving and it operates on exactly this kind of risk profile calculus....every time you take an aspirin depending on who you are you risk dying from a stroke or having some cross effect with a drug you have been taking.

Second, with regard to "designer" babies, his description of psychological traits as being extremely difficult to modulate is very on point...such things as we saw in "GATACA" where intelligence was directly modulated in a general way are unlikely how ever it can be modulate with much more gene specific changes that effect general intelligence for example changes that may control rate of neurogenesis (which are likely to be just a few genes over thousands) or changes that control memory formation by regulating certain key neurotransmitters....sure lots of testing needs to happen on these but we have an extant body of living people already expressing a full landscape of interactions of genes.

I've described some of this in hypothetical stories on the technology going back to 2008:

Understanding what we can do will come from looking at what nature IN us is already doing with no problem and simply replicating those patterns at earlier stages of development in target individuals.

Also, there are a bunch of designer baby changes that have nothing to do with enhancement but simply eliminate dangerous traits, for example susceptibilities to all types of genetic diseases have many well known genetic factors that can be singled out and edited with little reason for concern. Again, using the corpus of expression in living people to identify extant interactions is a great guide to avoid willy nilly changes ....and so having a rapidly improving ability to perform whole genome sequencing as well as characterizing patterns in those massive data sets to identify such patterns is a very good thing to be happening now.

Third, all the difficulties many in the bioethicist camp that feel a delay on research to germ line editing should be placed ignore the fact that many phenotype associated genetic changes can be made very few to no side effects at all. These would be the types that would be included in what I've termed cosmecutical changes. In my chapter of the book "The Future of Business" I provide a break down of some of the potential opportunities that loom in pursing development of phenotype targeted gene editing. The industry has a potential to be a trillion dollar industry inside of 20 years time. Coupled with it's relative ease to implement and safety compared to other gene line modifications as well as the potential social gains it makes a very big and obvious goal to advanced humanity along several lines that is worth the small risks.

Changes in this camp include edits to genes associated with the expression of melanin in the skin , eyes and hair...these would induce visible modulation of expression of skin types, hair color and eye color. I explain the social ramifications of such change in a few posts over the years but the advantage to society of the elimination of "race" as a fixed identifying element in the human family should be an obvious thing that we WANT to do and do as soon as we can. The age of "neapolitan people" as I've called it is important for us to mollify a great deal of the causes of xenophobia that exist in the world which are due to ignorance and fear based on differences in apparent morphology in phenotype.

Moreover, from the ethical perspective these changes are less ominous and also more potentially lucrative as targets to any researchers who are looking to take advantage of the technology...particularly in light of all the hubbub concerning modification to the germ line.

Finally such changes don't have to apply to the germ line at all, an advanced version of crispr used to precisely target and edit genes associated with skin color could confer temporary effects approximating a really long but genetically modified tan (but one where you can tan darker or lighter)...even that could be marketable and would likely have a demand space for it being done.

Highly targeted Cpg vaccine immunotherapy for a range of cancer


This will surely go down as a seminal advance in cancer therapy. It reads like magic:

So this new approach looks for the specific proteins that are associated with a given tumors resistance to attack by the body's T cells, it then adjusts those T cells to be hyper sensitive to the specific oncogenic proteins targeted. These cells become essentially The Terminator​ T cells in the specific tumor AND have the multiplied effect of traveling along the immune pathway of spreading that the cancer many have metastasized. This is huge squared because it means you can essentially use targeting one tumor to identify and eliminate distal tumors that you many not even realize exist.

This allows the therapy for treating cancer to, for the first time; end the "wack a mole" problem that has frustrated traditional shot gun methods of treatment involving radiation and chemotherapy ...which by their nature unfortunately damage parts of the body that are not cancer laden but …

Engineers versus Programmers

I have found as more non formally trained people enter the coding space, the quality of code that results varies in an interesting way.

The formalities of learning to code in a structured course at University involve often strong focus on "correctness" and efficiency in the form of big O representations for the algorithms created.

Much less focus tends to be placed on what I'll call practical programming, which is the type of code that engineers (note I didn't use "programmers" on purpose) must learn to write.

Programmers are what Universities create, students that can take a defined development environment and within in write an algorithm for computing some sequence or traversing a tree or encoding and decoding a string. Efficiency and invariant rules are guiding development missions. Execution time for creating the solution is often a week or more depending on the professor and their style of teaching code and giving out problems. This type of coding is devo…

AgilEntity Architecture: Action Oriented Workflow

Permissions, fine grained versus management headache
The usual method for determining which users can perform a given function on a given object in a managed system, employs providing those Users with specific access rights via the use of permissions. Often these permissions are also able to be granted to collections called Groups, to which Users are added. The combination of Permissions and Groups provides the ability to provide as atomic a dissemination of rights across the User space as possible. However, this granularity comes at the price of reduced efficiency for managing the created permissions and more importantly the Groups that collect Users designated to perform sets of actions. Essentially the Groups serve as access control lists in many systems, which for the variable and often changing environment of business applications means a need to constantly update the ACL’s (groups) in order to add or remove individuals based on their ability to perform certain actions. Also, the…
