you'll find egomaniacs in any industry. From experience the people who actually speak regularly at cybersecurity conferences do tend to have a "cult of personality" aura about them. Part of it is industry incentives too. If you have a bunch of stuff on Github / technical blog posts / social media presence it helps a lot finding a job. So I wouldn't necessarily entirely blame them for cultivating a social media persona.
