This is simply because it is an intellectual field that is not subject to professional norms of cognitive workers. You will likely find, if you read period pieces or biographies of similar situtations e.g. 19th century EM engineers, that they too had an inflated sense of the scope of their understanding of matters. This is likely (imo) due to the fact that mastery is gained somewhat independently and not subject to any pseudo-objective critical review (beyond 'my device x works!'), and no professional rigors are selecting for different (professional) mindsets. 'Those that don't know that they don't know' and all that. To amplify, a cognitive worker in an established discipline is buried under domain details and painfully aware of the scope of their field. They specialize, and are certified for that specialization. Their ego is better informed about the realities of their extent of knowledge, and yes, they paid dearly to get schooled and certified for their narrow niche. (So you have the inverse effect of possibly insufferable attitudes of experts regarding novel developments and ideas in their specialization.)
