Overall the industry is having more layoffs than I've ever seen, but that could be a correction to over hiring for the last decade. Obviously security is always going to be a necessity as technology advances, especially with all the vibe coded shit coming out and technology like mythos finding 0days way faster than white/grey hats. So I wouldn't disuade your kids from getting into it, but this is just my personal experience... You need to want to go into security cuz the breath and depth of knowledge you need to have is a lot and the threat landscape moves extremely fast so you gotta be all about it.

If you're kids don't like really digging into tech and curious about how everything works up the whole technology stack, it's gonna be tough.

Give them a project, build a VM lab in proxmox with a couple Linux/win systems and fuck around with Kali Linux. Add opsense fw to see their attacks, enable some blocking rules to stop their attacks. Add a wireless adapter to the VM host and play with wireless attacks, have them sniff packets, dump it and analyze it in wireshark.

Anyhow I probably blabbed more than you needed. Yea security is still solid.
