The claim is not that either “solution” is sufficient for counterfactuality, it’s that either solution can overcome the main bottleneck to counterfactuality. After that, per Amdahl’s Law, there will still be other (weaker) bottlenecks to overcome, including e.g. keeping oneself focused on something important.
I don’t think the social thing ranks above “be able to think useful important thoughts at all”. (But maybe otherwise agree with the rest of your model as an important thing to think about)
[edit: hrm, “for smart people with a strong technical background” might be doing most of the work here”]
