Meaning, that if the technique was fully viable in humans, ethically approved and widely practiced it would start to have measurable impact 25-30 years from now. Each iterative improvement step would take two decades.
Genetic modifications are much too slow for the kind of progress I'm expecting for the next ~50 years. Genetic modifications are thus just a fallback option in case multiple technology branches fail dramatically. (Which would currently seem to require a truly global screwup of Holocaust caliber and is thus of no interest to us because we'd be dead or close to it).

I was dismissing recombinant DNA techniques a priori because they are much too slow, and do not at all help people already born (it is not exactly safe messing around with quantitative transfection vectors which activate diverse morphogenesis boxes *in adults*). What I was referring to difficulties in intelligence enhancement I specifically meant those involving building brain implants.
You need nano for really useful brain implants (have you ever tried sticking a million of bionert wires (with big computers attached on the other end) into a semifloating baloon made out of jelly?). It is hard even with nano. Also, by that time you can begin to do that, you can churn out building-sized blocks of bucky circuitry. The disparity would seem pretty apparent. Somebody is surely going to do something with all that computer power.

Provided you can do nontrivial brain implants, you will need hyperplastic brains which currently only exist in neonates/ toddlers. It might be possible to rejuvenate brain tissue and throw it into hyperplastic mode with a very advanced drug cocktail, but I'm not counting on this too much. To wit: you require already two nontrivial ingridients: nano and the magic drugs.

Yes, but certain contexts will turn out to be pretty expansive, on the cost of other contexts. (It would seem to be a very good strategy to try to identify such contexts early. If you can't beat 'em, try to join 'em).

Both seem much harder than building a Golem.

Exactly. When personal survival is at stake, assuming a worst-case scenario is the only prudent approach. (Especially considering the cost/benefit ratio, and the "bus driver waiting for the bus" scenario (it may sound silly, but really, nobody in the civilized world is doing it. Also, consider the current bottleneck in cryonics service providers, currently only CI and Alcor being available. Did I already mention eggs/baskets?)).
Also, I happen to think there might very well be a coevolutionary race scenario between uploads and AIs. Even if chances be slim, being there first can make an universe of a difference. The lowest-tech approach to uploading is currently FSS (freeze, slice, scan). While we more or less know how to tackle the to S's, with the resources at our disposal focusing on F has the best cost/benefit. Currently.
