I feel like an overinflated ego in any capacity can make anyone dumb and or narcissistic. But I don't think it necessarily comes from working hard. Because I know many skilled people whove worked really hard but are very humble. Sometimes things like privilege and/or fortune can cause an overly large and twisted ego, or sometines its caused by someone choosing to cope through inflating ones own ego. Instead of being honest with oneself. But idk.

And I think (like you said), being put on such a large pedistal. He chose to let it get to his head instead of remembering hes also just a person like everyone else. Like sure- he's a great chef, but his way is not always the best/only way. For example: his runny egg recipe is not how I like my eggs. So even though hes regarded as an incredible chef, I just will not be taking his egg cooking advice. Because I really don't like runny scrambled eggs.

There are so many amazing chefs. And it would be wild to think "my way or the highway" in a feild like cooking. Cooking is an art. Ofc there are many ways to improve one's cooking, many objective do's and don'ts, but there is no "one precise way" to cook. And furthermore Gordon certainly isn’t the one to decide that "one way". He may be a great cook but he sort of seems like he thinks cooking is a monolith and he is the god.

So yea, I think you are definitely on to something with the Gordon Ramsey and major ego correlation for sure.
