ChatGPT has told us:
No, gifted people do not know everything. Giftedness typically refers to individuals who demonstrate exceptional abilities in one or more areas compared to the general population. However, this does not mean they possess knowledge in all areas or that they are experts in every subject.
Like anyone else, gifted individuals have their own unique strengths and weaknesses. They may excel in certain areas but struggle in others, just like anyone else. Giftedness is not a guarantee of expertise or omniscience, but rather a potential for exceptional talent in certain areas.
