I've updated Arch systems that were years behind, and everything went just fine. In fact, I've had many failed Debian/Ubuntu dist-upgrades, where I ended up giving and reinstalling. I've definitely ran into trouble with my Arch installs too, but they were easily fixed.
The thing with Arch is once you're comfortable with it, it doesn't really matter if it breaks. It's as easy to fix as it is to break. Just make sure you don't need said laptop for something critical right after an update so you have some time to deal with it. But realistically, you'll be fine.
If you're really worried, set up automatic snapshots so you can easily revert a borked update in a pinch.
For everything else, there's containers: be it Podman, Docker or systemd-nspawn. Nowadays there's also Flatpaks if you have an app that really doesn't want to play nice with Arch.
10 years and counting on Arch. Desktop, laptop, servers, no issues. Never felt the need to distro-hop apart from trying out NixOS in a VM every now and then just to see if it clicks yet.
That said, being fluent with multiple distros is never a bad thing. If I have to set up an unattended set and forget box, I'll still turn to Debian with auto updates enabled. It seems like at least you're not constantly reinstalling all your machines, which is typically the problem with distro-hopping.
