Autist people like to put one thing on the other (see more about autism and repetive behaviour in https://www.autismspeaks.org/science/science-news/study-suggests-repetitive-behaviors-emerge-early-autism) Recursive self-improvement is the same idea on higher level. That is why nerds (me too) may overestimate the probability of such type of AI. Sorry to said that.
At some point soon, I'm going to attempt to steelman the position of those who reject the AI risk thesis, to see if it can be made solid. Here, I'm just asking if people can link to the most convincing arguments they've found against AI risk.
EDIT: Thanks for all the contribution! Keep them coming...
