I have noticed that when the AI gifts certain research specializations, it can be more of a curse than a gift. For example, for the research optimization specialization, one of the choices is "sustainable research" which reduces the maintenance cost of research improvements by 10%. This is a negligible bonus compared to the specialization that increases research by 10%. I had "sustainable research" gifted to me by the AI, and therefore was stuck with it as it can't be declined. There should be an option to decline such "gifts". But I think it highlights issues with a lack of balance in the research specialization choices more generally.
