It is evident that they need more than five categories. Awarding Nobels to individuals who are not particularly (if at all) well-versed in the subject at hand, even if they contributed to a breakthrough in the field, directly or indirectly discredits the prize. Indeed, the online memes about Hinton and Hassabis being "a bit of a <physicist|chemist> myself!" are justified, in my opinion.
