Just being cautious about security non-disclosure agreements. It is possible to inadvertently disclose client vulnerabilities by discussing how certain specific skills are necessary, how precarious certain environments are and how fragile they can be without said skills. It is also possible to alert bad actors to the fact that certain skill sets are a weak link in certain client's infrastructure.

If you are a teenager with a very strong knack for synergy, build crafting, etc., please consider pointing your obsessive mind towards technology (not software development or tech support).

Imagine enterprise level applications as complex living organisms where one insignificant misconfiguration in a peripheral and, as far as everyone was concerned, unrelated system can snowball into bringing down and entire service provider. Sure, someone will eventually do an incident investigation and maybe figure out what went wrong back then, but it is far more valuable to have people that can look at a set seemingly unrelated and not at all concerning metrics and flag the lot as a priority action item BEFORE the system crashes. It seems like black magic fuckery to some, but what it really is about is a combination of deep and wide knowledge of all moving parts related to the application, experience, and the ability to think holistically and understand the synergies.
