Ask HN: Will I ever feel like I know "everything" about web programming?

I am a fairly technical person. Bachelor's degree in Computer Science and have a solid understanding of the building blocks of computer science and the web. I "learned" programming in college, but when I graduated I felt like all I could do is just build random projects - which is what I did - in languages I considered 'archaic' and uninteresting to me (largely C, C++, Java, Assembly, etc.). I am not starting a flame war, but those languages are just not interesting to me - or rather, they weren't until I stumbled upon Ruby. I learned OOP via Java and hated it. Over the last 3 - 4 years I have been teaching myself Ruby & Rails dev. I am loving every minute of it - but I am a bit self-conscious about my development skills because I know how much I don't know. I am not one of those guys that has a huge Github repo and actively participates in lots of OSS projects. But if I want to build something, no matter how long it takes me - I figure it out. I can't say it's always "very elegant" the first time, but there is always a desire for me to make it so. Is it normal that 3 years into Ruby & Rails development I feel like I still have A LOT to learn? Will I ever feel like I know "everything" there is to know about Ruby, Rails, OOP, etc.? The more I learn Ruby is the more I find myself looking at other languages to see how things are handled in those languages, which also leads me to start thinking about languages (both programming and natural/spoken) and the way they are constructed and other things outside of web programming. But then I just stop because I already feel a bit overwhelmed with the amount I have to learn about the web. I know this may be a bit subjective, but I feel torn. I don't know if the way I am feeling is a good thing (i.e. because I know what I don't know, I am always trying to improve my craft) or a bad thing (that I am learning too slowly - I do tend to take the long route because I want to make sure I thoroughly understand what I am learning).
