I think somatic gene therapy, while technically possible in principal, is extremely unpromising for intelligence augmentation. Creating a super-genius is almost trivial with germ-line engineering. Provided we know enough causal variants, one needs to only make a low-hundreds number of edits to one cell to make someone smarter than any human that has ever lived. With somatic gene therapy you would almost certainly have to alter billions of cells to get anywhere.
Networking humans is interesting but we have nowhere close to the bandwidth needed now. As a rough guess lets suppose we need similar bandwidth to the corpus callosum, neuralink is ~5 OOMs off.
I suspect human intelligence enhancement will not progress much in the next 5 years, not counting human/ML hybrid systems.
Mostly, a useless dead end. The big problem is even assuming it's socially acceptable to do it, the stuff genetic engineering can do is either locked behind massive time and children investments, or is way too weak/harmful to be of much use. It's an interesting field, with a whole lot of potential, but I'd only support expand it's social acceptability and doing basic research right now, given that I see very few options for genetics.
Also, how much somatic gene editing, not how much gamete gene editing is the key taut constraint.
There's interesting possibilities with BCI that you don't list. But the bandwidth is too low due to the butcher number. https://tsvibt.blogspot.com/2022/11/prosthetic-connectivity.html
Not doing things because AGI comes soon is a mistake: https://tsvibt.blogspot.com/2023/07/views-on-when-agi-comes-and-on-strategy.html
Germline engineering is feasible, but society anti-wants it.
I have been wondering if the new research into organoids will help? It would seem one of the easiest ways to BCI is to use more brain cells.
One example would be the below:
Pretty positive. I suspect that playing a lot of ordinary video games as a child contributed at least somewhat positively to my current level of fluid intelligence.
Playing games or doing training exercises specifically designed to train fluid intelligence and reasoning ability, using a BCI or other neurotech, seems like it could plausibly move the needle at least a bit, in both children and adults.
And I think even small enhancements could lead to large, compounding benefits when applied at scale, due to better coordination ability and general improvements to baseline sanity.
Maybe, in-vivo genetic editing of the brain is possible. Adenoviruses that are a normal delivery mechanism for genetic therapy can pass hemo-encephalic barrier, so seems plausible to an amateur.
(Not obvious that this works in adult organisms, maybe genes activate while fetus grows or during childhood.)

This post contains the most in-depth analysis of human intelligence augmentation (HIA) I have seen recently, and provides the following taxonomy for applications of neurotechnology to alignment:

Outside of cyborgism, I have seen very little recent discussion regarding HIA with the exclusion of the above post. This could be because I am simply looking in the wrong places, or it could be because the topic is not discussed much in the context of being a legitimate AI safety agenda. The following is a list of questions I have about the topic:
EDIT: "We have to Upgrade" is another recent piece on HIA which has some useful discussion in the comments and in which some people give their individual thoughts, see: Carl Shulman's response and Nathan Helm-Burger's response.
