People shouldn't learn things for their own pleasure or satisfaction?
I think it would be a mistake for CuriousCarrot to study Encyclopedia Britannica because it is too broad to learn arbitrary facts like that. Or take Astroman707 for example, he was a teacher, becoming a theoretical physicist, thinking about coding, he should keep his focus which I think he is, but he is also wondering if he needs quantum field theory because astronomers don't seem to need it. His questions are headed in more or less the same direction because he is in that period between choosing a career and being able to work in it. He is not also studying Encyclopedia Britannica. If he was, I would say he is distracted from his purpose.
But if he said, I have a passion for American revolutionary history and am learning that on the side, I would say that is okay, but the desire for success should drive him to learn and master his profession so he can succeed. He should not allow himself to be distracted by things that are not relevant.

@astroman707 I would say, learn quantum field theory if you need it. If you don't, learn it only if it interests you but don't let it be a distraction.
The first point I want to make is: we all need to succeed at life sooner or later. No one can work impossibly hard; we need recreation and we need financial freedom (among other things). And to get those things, one needs to choose a career and make a success of it. And this should drive one because it is so important to reach that point where you are over the hump. From then on it's easier.
Of course it is important to pick a career that one has a real passion for, that one can see oneself feeling proud to be associated with, etc. It's a very important choice to make but success in that chosen career is very important.
Second, science is both a body of knowledge and the practice of generating that knowledge. Choosing a career and studying should be to become the person who not only knows but practices as well. That is the point. I know a lot about computers, trust me I do, but I get to use them every day. The reason I chose computers is because I had a real passion for them and I knew I would always be using them, whether or not I chose it. I worked very hard to make a success of it and that is what we all have to do. And if it doesn't work out, know that you gave it your all. Don't leave stones unturned in your pursuit so that you can move on with pride that you achieved what you did achieve.
I think CuriousCarrot would miss out on stuff like this if he doesn't get serious about his life and his goals.
As for the general point, should we learn recreationally, by all means do it. But should we learn encyclopedicly, no, I don't believe so. I think as recreational learners we should follow our interests. Does that make sense? This is what I meant when I said "only".
