This video has a lot of self-hosting and somewhat advanced stuff being mentioned, but if all you want to do is start dipping your toe into Linux then it’s not nearly as hard as you’d think. I would try running Linux in a VM (i.e. VirtualBox) to get a feel for how it operates and build up confidence that way, as well as maybe watching some videos on how people set up and use their Linux etc. It will be a learning curve, but as long as you pick a beginner-friendly distro (e.g. Linux Mint) it’s really no more difficult than if you started using Windows for the first time. Keep backups of your data and/or put Linux on a secondary computer and you should weather the initial few weeks just fine.

On the upside, when you have problems in Linux there will be logical solutions with answers that can be searched for, whereas in an OS like Windows or Mac the solution is probably “I dunno! Reinstall?” or “You just can’t do that, sorry”. It’s also understandable if you don’t want to touch anything complicated, but I do think one of the best parts of Linux is really just getting messy, making mistakes, and learning. Because things in Linux make sense, over time you’ll learn how to use a computer again. I feel strongly that Windows/Mac/Android/iPhones have (intentionally) dulled the average person’s computing skills and put them into a state of learned helplessness. Everyone thinks computers are complicated wizardry because nothing on those proprietary operating systems makes logical sense, and trying to troubleshoot anything results in wasted time and frustration.
