Linux

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.
