Don't get me wrong. I love Linux and FOSS.
I have been using and installing distros on my own since I was 12.
Now that I'm working in tech-related positions, after the Reddit migration happened, etc. I recovered my interest in all the Linux environment.
I use Ubuntu as my main operating system in my Desktop, but I always end up feeling very limited. There's always software I can't use properly (and not just Windows stuff), some stuff badly configured with weird error messages... last time I was not able to even use the apt command. Sometimes I lack time and energy for troubleshooting and sometimes I just fail at it.
I usually end up in need of redoing a fresh install until it breaks up again. Maybe Linux is not good for beginners working full time? Maybe we should do something like that Cisco course that teaches you the basic commands?
I think the issue is that while Linux is capable of a lot when you can take full advantage of it, each task requires way more knowledge or a good tutorial and no complications.
For me, I love working with Linux and have been doing it on and off for decades, but it doesn't tend to remain my daily because of the extra steps and limitations.
I think if I had a more full working knowledge of Linux and I knew Python or had a stronger grasp of other languages, I'd be a lot more able to fill those gaps. But without that, it there are all these barriers to productivity that aren't there otherwise. Instead of doing the thing I'm trying to do, i end up spending the night messing around with some depreciated program or struggling with a weird use case and it simply requires way more of my time to get there.
Considering that I have a lot more experience with Linux than the average person and still run into this regularly, I'd say it's a big barrier to wider adoption.
Honestly the solution is probably more on the end of getting together to make some of these issues less complicated than on the end of expecting everyone to become a well versed Linux enthusiast. With such a high learning curve, unless you're using it for something it's particularly good at doing easily, you kind of have to want to get into Linux for its own sake in order to learn enough to make it easier to use. And even then, it's a struggle sometimes.
Ultimately I agree. Open source software is the only software that's sustainable and that benefits humanity in general more than it benefits some company somewhere. I choose open source software basically whenever I can. I hope that some day in the future that'll extend into operating systems for personal computing and game servers, but unfortunately that's not the case at the moment for my use cases.
