Just install an LTS kernel instead of the latest one. Unless your hardware was made literally yesterday you'll be alright, and the number and frequency of updates isn't far from, say, Ubuntu at all.
Also use archfi. It's a super easy and reliable way to get an Arch install going.
I typically do a timeshift snapshot before doing a $ pacman -Syu, just to be on the safe side. Im on arch since ~3 months now and so far it's been rock solid
Been too lazy to timeshift but I have backups of stuff I need if my system is bricked.
Arch hasn't broken on me in well over a year but my system is pretty lean anyway
