I've been using Linux for 27 years, and it hasn't changed all that much in that time. Packaging has got better, systemd is a bit of a pain in the tits but necessary if you want to support the kind of things we expect to do with "real" computers instead of servers sitting in a dark room untouched for years.
I've been using NetBSD for about the same amount of time, and it hasn't changed all that much either.

First there's networking configuration. On Debian and Ubuntu the interfaces(5) used to be nice and simple, but dog knows what to use on any particular system nowadays since there are like three ways to do things: interface, netplan, system-networkd, other?
Plus there's resolv.conf(5) being fiddled with a myriad of ways and you have to figure out which system to use there as well.
ifconfig kind of works and kind of doesn't for some things.
How may firewall system changes have there been in the last 27 years? Are we supposed to be using iptables or nftables in 2022?
In roughly the same amount of time I've owned about ten or fifteen cars.
Every single one of them had the dashboard controls in slightly different places, with slightly different options. Some had four-speed gearboxes, some five-speed, some automatic with three-, four-, five-, or in one case 18-speed gearboxes.
Every single one of them was basically just a car, and drove me to the same places in the same way.
