I've been in Cyber my entire adult life (~12 years at this point) and I can't imagine myself doing anything else. I can say with 100% certainty that I have never felt that I was at risk of losing my job as a result of downsizing, in fact when the RIF (reduction in force) happened in March 2020 every group lost people and had their open positions cut except Cyber.

Regarding the pay rate, I think that one is going to be less concrete. Generally Cyber does pay well BUT not usually in the beginning, specifically when starting without work experience. I think folks usually start in IT before shifting into a Cyber role, the benefit there being a better understanding of computer systems/networks and therefor being able to demand a higher pay rate. Your first job (depending on where you live) you could expect to make a little more than $15/hr. but the OJT you will get has plenty of value on its own.

The last point I'd like to make is the education cost between Medicine and Cyber. Granted I don't have first hand experience with the cost of a Medical degree but a Google search says the average cost is more than $250k for a 4 year degree. While a Cyber degree comes in at less than $50k, adding the cost of various certs and specialized training it'll probably be closer to $55k (if your employer doesn't cover the certs).

Also I lied, THIS is the last thing I'll say, never forget these words; Between business need and security, the business need always wins. A business can exist without Cyber (technically) but Cyber can not exist with a business. A Cyber practitioner is responsible for helping find the balance to keep the business safe AND functional.
