There’s a difference between corporate IT and being a computer geek.
I agree that many IT careers are relatively simple support jobs.
OP mentioned computer geeks, which implies to me, people who are deep into computers. In that light, if you’re struggling with concepts of IP addressing then the more-complicated facets of computers and networks will preclude you from an engineering role.

Ya it’s me I’m the guy in IT who is currently confusing a subnet mask for my own ass.

Just think of it as a routing optimisation that is only relevant for ipv4 networks.
Router simple, router need to make decisions quick, quickest decision is made when can smush the subnet mask against an IP address and determine if the computer is on a local network so router can send traffic direct or is on other network so router needs to send traffic to other router
