Twenty years ago when I was 13, I started doing web stuff. This was back when everything was super simple, so everything to get a webserver up was super manual. I’ll mention port forwarding at my current job and there’s this slice of people that are 28-40 years old that know what I’m talking about.
I’m slightly younger than that even, currently finishing up my master’s but have been working as a backend dev for a couple of years.
I’ve learned an order of magnitude more about networking from just being in the vicinity of my girlfriend (who is a network technician) than from uni, and it’s definitely already paying off.
